KPNO nights 3 and 4

Hello, my name is Alexander Dillaire and I am a junior Astrophysics major at Haverford College. Tonight is the last night we will be staying at Kitt Peak; we fly out tomorrow morning. So far this has been a phenomenal experience, with no shortage of excitement. Last night, we had major technical issues that almost forced us to stop collecting data. I might be exaggerating a little on that part, but not too much. Unfortunately, the first instance of serious trouble came when I was the main person collecting data. That was really frustrating. Luckily, we tackled the problem by side-stepping the issue. It took more effort on our part, but it made things much smoother.

We also took pictures of two celestial bodies, M33 and Barnard 33. M33 is a spiral galaxy and Barnard 33 is the Horsehead nebula. All of our images came out well, which was really a highlight of the night. Both are great to look at. My partner and I are planning to make posters with our pretty images for our personal enjoyment. It was a blast taking the pictures, even if the exposure time was long. 9 minutes is a long wait for a cool picture, but they were worth it.

Tonight, we have not had much technical issues. We kept the solution from yesterday and so we are diligently taking notes. The data we are collecting from the CCD camera is turning out well, there’s just a lot of work to be done and it’s very repetitive. It’s all in the name of science, so it’s a burden we are willing to take. Overall, I think that this has been a wonderful experience. I mean, seriously, how often do you go on field trips in college. It’s the greatest. Just shows how awesome being an Astrophysics major at Haverford College is.

KPNO night 2

My name is Erica Hopkins and I’m a junior astrophysics major. Tonight was our second night observing at Kitt Peak. We had good observing for most of the night, however it got cloudy near the end. We got over a dozen images of Palomar 13 in both V and B band and a few images of Ursa Major II. Ursa Major II is only up for a short time and we lost some of that time due to bad weather. Overall it was a successful night and we look forward to continuing our observations the next two nights.

Observational Astronomy Class Trip to Kitt Peak –Night 1

Hello from Kitt Peak National Observatory!  My name is Sarah Sofia and I am a Junior Physics/Astronomy major at Haverford.  I am here observing with Haverford’s Observational Astronomy class.  We are currently on our second night of observing on the 0.9 meter telescope at Kitt Peak taking data of Palomar 13 and Ursa Major II, looking for RR lyrae variable stars.

Although we had a few struggles with weather and equipment problems our first night, we had a great night of observing.  We had a big set back at the beginning of the night after the CCD camera had warmed up significantly, making our images unusable.  However, with a lot of refilling of the dewer by my classmates, the camera was cooled back down and we were back in business for observing.  There were a few other setbacks in the night like setting off the dome alarm (DON’T hit the emergency stop!), persistent cloud cover, and Mimi and I even managed to get lost on our way to the dome (it’s VERY dark out here at night).  Despite all that, we managed to have a fun, productive time observing.  Because of the unfortunate cloud cover, we were unable to take good data of out targets.  This, however, allowed us to take some beautiful pictures of the crab nebula and the orion nebula that made the long night completely worth it.

Tonight, the observing has been fantastic with a seeing of about 1.5 arcseconds.  The night is absolutely beautiful up here, and we have been periodically standing outside to gaze at the crystal clear night sky, clearly seeing the milky way and stars we can never see at Haverford.  We’re getting great data of Palomar 13, and hopefully will continue to throughout the night.

Interning at the Astronomical Society of the Pacific – Miriam Fuchs ’13

Greetings from San Francisco! My name is Miriam Fuchs, and I am a senior Astrophysics major at Haverford College. This summer I’m interning at the Astronomical Society of the Pacific (ASP), a non-profit dedicated to increasing science literacy through astronomy education. After spending the previous two summers conducting astronomy research, I wanted to try out astronomy education and see how I liked it.

So far, I’ve been having a blast! I’ve been fortunate enough to get my hand in a few different areas of astronomy education and outreach. My main focus for the summer has been multicultural astronomy education. Astronomy has been an important focus for cultures throughout the centuries; how can we incorporate cultural models of the universe and observational methods into current astronomy education? I’ve been attempting to answer this question in a few different ways. One way is through updating a multicultural astronomy resource guide compiled by Andrew Fraknoi in 2008. For a variety of cultures, there are different activities, articles, links and general information for educators to turn to. More recently, I’ve been helping developing a multicultural astronomy activity to be used in two upcoming teacher workshops. The activity is based on calendars throughout the ages and how did different cultures marked the passage of time through astronomical observations.

I’ve also been able to get some more hands-on outreach experience at a myriad of local astronomy programs and events. In early June, I worked at Lawrence Hall of Science in Berkeley, CA for the Transit of Venus. Over the course of the afternoon, around 3,000 people showed up! I showed visitors how to use the solar telescopes and answered questions about planets, transits and general astronomy conundrums. Here’s a photo of a family using one of our solarscopes:

Later in the month, I worked at a SETI convention where I got to have an incredible conversation with Dr. Frank Drake (of the famous Drake equation), and discuss my interest in astronomy.   Definitely a highlight for the summer. Last week, I helped run a supernovae session at a local NASA Space Art Summer Program for high school students. Here’s a photo of the students participating in an activity called “The Kinesthetic Lifecycle of Stars” (they had just gotten to the supernova phase!):

I just got back from a weekend training workshop of the Bay Area Project ASTRO. Project ASTRO is a national program to improve science education through linking professional and amateur astronomers with local classrooms. At the workshop, we trained over 20 local astronomer/teacher pairs about different ways to teach astronomy in the classroom. We went over different methods of teaching science, innovative astronomy activities, and how astronomy/teacher partnerships can benefit students of all ages. It was an incredible experience that I am proud to be a part of. Here’s a photo of two astronomers and a teachers working on a scale model of the solar system:

I was fortunate enough to receive conference funding from Haverford to attend the ASP’s annual conference entitled “Communicating Science” in Tucson, AZ in early August. I’ll be presenting a poster there and helping facilitate a teacher training workshop.

All in all, everyone at the ASP has been incredibly inviting and helpful, whether it is inviting me to work on one of their projects, sharing their stories about how they got involved in astronomy education, or introducing me to useful contacts. I went into this summer considering a possible career in astronomy education and outreach, and my experience so far has pretty much solidified this notion. I’m excited to go back to Haverford in the Fall and share my outreach experience with my peers!

Space Astronomy Summer Program 2011 at STScI

Hello, I am Tonima Tasnim Ananna, a Bryn Mawr Physics and still undeclared Haverford Astronomy major. A week ago, my internship at STScI ended. Too many amazing things happened that I am grateful for, and here are some (non-project related) highlights of my summer:
– Met John Grunsfeld in person, he serviced the HST three times, and is a prominent cast member of the Hubble IMAX movie. He sent his application for the Deputy Director position (of STScI) from outer space, and of course he was hired. He is a really fun speaker too.
– Met Adam Reiss, the co-discoverer of Dark Energy. We worked on a problem set (Problem set # 4, Modern Galactic) at Haverford based on his historic 1998 paper.
– I met Alberto Conti, the person who proposed the Google Sky project to Google. He is Italian, as was my mentor Massimo Robberto. There are a lot of Italians working at STScI. It’s nice to see Galileo’s legacy being carried on.
– Took a trip to Goddard Space Flight Center. We saw the gold mirrors of JWST being assembled! Our tour guide was the ‘Stock Ops’ (who sends out the final command to the astronauts) of the 2009 HST servicing mission, and he told us details of the mission. While we visited Goddard, on account of being a non-citizen, they gave some of us a shiny ID badges, but sadly took them away when we were leaving 
– My mentor co-wrote the script for the Hubble Imax movie (because he is the Orion Nebula guy at STScI), and he told me that Leonardo DiCaprio left out the part about the trapezium of stars because apparently he couldn’t see a trapezium.
– Met a Bryn Mawr alumna, Jennifer Lotz, at STScI. She remembers Steve Boughn! =D
– Lisa Frattare, SASP organizer, said we have a lifetime supply of HST lithographs and posters, we just need to ask them and they will mail it to us. Some interns were planning to start an ebay account selling HST posters, but I don’t think they will actually do it.

There are a couple of cool things that I am missing, but I should move on to my project. I think I was able to make a significant amount of progress on making the Orion catalogs this summer. When I started out, there were so many problems with the magnitudes of the sources, the images of sources in the catalog, monster error bars etc. As I have mentioned in a previous post, there were 5 detectors in which the Orion was imaged, and my mentor Massimo pointed out some problem in the ACS catalog and got me started. After that, I found problems and made changes in the other catalogs by myself, and in the end he told me he was very happy with the catalogs and the Atlas. I added more comments and changed the layout of the final Atlas so a lot of details about the sources and the images appear in the Atlas as well. There are some isolated problems that I left for him because I only had a finite amount of time, but I have flagged all that I could find and didn’t have time to solve, and the data should be ready for publication after he checks these. Massimo says a catalog with more than 8000 sources would never be 100% error free, but if we can hit 95%, he’d be happy.

If it’s not clear what I mean by the Atlas and catalog, this presentation might help clarify: http://prezi.com/gl45yozphnf4/final-the-hst-treasury-program-on-the-orion-nebula-cluster/
More specifics about the changes I made also appear in the presentation. I hope everyone had as wonderful a summer as I did!

“Inspriting Every Child with Our Wonderful Cosmos” : Working with UNAWE –Maya Barlev ’12

Hi Astronoblog readers! Maya Barlev here, Haverford astrophysics major, and member of the class of 2012.

This summer, I’m working with Universe Awareness, (UNAWE), an international non-profit organization that aims to “inspire every child with our wonderful cosmos.” UNAWE works in 40 countries around the world, primarily in disadvantaged communities. With the support from Haverford’s Center for Peace and Global Citizenship, (CPGC), I’ve been working as an intern at UNAWE’s headquarters in Leiden, the Netherlands.

As an intern, I’ve designed a board game about light and the solar system, written a “how-to” guide for people wanting to start their own local UNAWE program, developed ideas for a UNAWE program in the United States, written updates for the website, and much more. While I haven’t been working directly with children, I have been spending a lot of time thinking and writing about how to successfully communicate science with young kids.

One of UNAWE’s main goals is to connect science and social justice by teaching children “unity under one sky.” Despite location or circumstance, children all belong to the same globe, and observe the same Universe. This aspect of UNAWE is what sets it apart from any other astronomy outreach organization, and what drew me to it in the first place.

Through working with UNAWE, I have gained a greater idea of what I’d like to do with my astrophysics major in the future. I love astronomy, and have loved doing research, but what I enjoy most is giving and sharing what I know. I would love to work with organizations like UNAWE in the future to share my knowledge of astronomy with those who may not be able learn about our amazing Universe otherwise.

The UNAWE office is located within the Leiden University Sterrewacht, or astronomy department. Leiden is world-renowned for its astronomy, with such famous scientists as Ehrenfest, Lorentz, (for which my building is named after), Snell and Oort as alumni and faculty, and Einstein as a regular visiting faculty member. There’s a wall in the department signed by important physicists and astronomers, and it was really amazing to see the handwriting up close of N. Bohr, A. Einstein, etc. :

Currently, the department is still kickin’, with about 40 faculty members, and over 60 PhD students. Earlier in the summer (before people went on vacation), I regularly attended astronomy talks and colloquia. Also, I have made some great friends with PhD students, and have learned a lot about what it’s like to pursue a degree in astronomy.

So, all in all, it has been an amazing summer. I feel grateful for the opportunity to travel abroad, and learn about astronomy and outreach in a new way!

Summer Research: Emily Cunningham ’12, Harvard-Smithsonian Center for Astrophysics

Hello, my name is Emily Cunningham and I am another rising senior participating in summer research. This summer, I am working at the Harvard-Smithsonian Center for Astrophysics, with Dr. Francesca Civano on pairs of X-ray sources in the Chandra COSMOS survey.

The COSMOS field is a region of the sky that has been surveyed in over thirty different wavelengths, resulting in a wealth of data on the sources in the field. The X-ray sources I am studying are active galaxies. While active black holes are often obscured by dust or light from the galaxy, there is the least amount of obscuration in the X-ray. As such, detection in the X-ray is the best way to unambiguously identify an active galactic nucleus (AGN). Therefore, we can use the data from the Chandra COSMOS survey to identify pairs of AGN and the data from other COSMOS surveys to study their properties in detail.

While I am very much enjoying the science, my summer here has been so much more than simply a research experience. First of all, the program itself has many components to help us prepare for our future careers in astronomy: the SAO REU aims to give its students a window into what life as both a graduate student and an astronomer is like. We have had lunch discussions on how to apply for NSF fellowships, what the application process is like for graduate school (from both current Harvard graduate students and Harvard faculty on the admissions committee), and about research ethics.

In addition, we have multiple opportunities to interact with many of the amazing astronomers that work at the CfA. Every Thursday afternoon the interns host a colloquium: we have seven speakers throughout the summer, each engaging in a different kind of research in astronomy. Each week two interns host the colloquium, and are responsible for meeting the speaker ahead of time, arranging for the food and beverages, and introducing the speaker. It has been wonderful to meet members of the CfA community, learn about some of the different fields within astronomy, and to have a brief opportunity to practice speaking in front of large crowds.

The writing experience has also been very valuable. Over the course of the summer, each SAO intern produces a paper on their research project, and gives a 15 minute talk on the research at the end of the summer. We produce three drafts of our papers: the first three weeks in (Intro and Methods), the second, a full draft, seven weeks in (due next week!), and the final draft due at the end of nine weeks. It has been wonderful to be able to develop my scientific writing skills and to have conversations with multiple experienced astronomers on both my writing and my project.

Above all, however, I am grateful for my relationships with the other students in the program, both the Astronomy REU and the Solar Physics REU (including the delightful Andrew Sturner). One of my favorite parts about studying astronomy at Haverford is our tight community of students: we work together and learn so much from one another. I’m thrilled that I have found another such community here. Even though we are working in many different fields and in many different programming languages, we still rely on each other for proofreading papers, debugging code, or talking through concepts. In addition, we all live together in Harvard graduate student housing, so we often cook together and explore the area together. Our adventures have included the Boston Aquarium, the Fine Arts Museum, Provincetown, Wonderland Beach, and Chinatown, and we will be going to stay at my house in New York City next weekend! I am so happy to have the fellow interns, both as friends and as colleagues, and will no doubt maintain these relationships for a long time.

Summer Research at BU

Hi everyone!  My name is Miriam Fuchs, and I’m a junior Astrophysics major at Haverford.  This summer I’m working with Professor Andrew West (HC ’99) in the Astronomy department at Boston University.  So far it has been a blast!

My research focuses on white dwarf and M dwarf binary pairs.  Using spectroscopic data from the Sloan Digital Sky Survey, we are able to look at multiple spectra of each binary that have been taken over a short period of time.  Over the course of a couple of hours, each binary will typically have 3-8 exposures taken.  Because these binaries are so close together and moving so quickly, their spectra will have visibly shifted from one exposure to the next.  Because of this, we can use Doppler shifting to calculate the radial velocities of the white dwarfs and M dwarfs and learn more about their general kinematics.

Working at BU has been an exciting experience.  Having multiple floors of astronomers, and lots of grad students to consult has definitely highlighted some of the differences between working at a large research university and a liberal arts college.  It’s also been great working with a Haverford alum – while I’m no longer in the basement of the INSC, it still feels like a Haverford lab; there’s a lot of collaboration between professors and students, everyone helps out one another, and there’s a general sense of being part of a community within our group.  More than anything else, my research experience this summer has taught me how much I enjoy conducting research.

Being in Boston also has its perks! There’s delicious food all around, great museums, and lots of things to do. Later in the month, our lab is taking a group field trip to Fenway to watch a Red Sox game – I’m really excited!

All in all, it’s been a fantastic summer so far.  It’s been great reading everyone’s updates on the Astronoblog.  Hope everyone else is having a wonderful summer!

 

2011 Summer Research – Jacob Gilbert, Swarthmore College

Hi! I’m Jacob Gilbert, another one of the rising seniors in the department, majoring in Astrophysics. I’m working through the Keck Northeast Astronomy Consortium at Swarthmore College with Professor Eric Jensen, studying the youngest exoplanets in the galaxy. We are working under the auspices of the Young Exoplanet Transit Initiative (YETI) to try to learn about planetary formation models. YETI uses over 20 different telescopes around the world to try to continuously monitor stars with orbiting exoplanets.

Here at Swarthmore we have been observing several stars; some have known exoplanets, whereas others are candidate stars that we are looking into further. When we observe these systems, we cannot directly view the planets. What we look for instead is how the brightness of a star changes with time. When a planet passes in front of a star, it transits the star, which appears dimmer to us. When the star passes to the side, it reflects light back at us in a subtle effect known as occultation. We are only looking at the transits, as our telescope is not sufficiently precise enough to measure the small increase in brightness caused by an occultation.

Most of the work I have been doing during the daytime has focused on writing code (unsurprisingly) to reduce the images taken at the Peter van de Kamp observatory here at Swarthmore. Since the code was written in IDL, I’ve mostly been fine-tuning my IDL coding skills, especially with regards to graphical interface. What started out as a simple image reduction code now reduces the data, performs aperture photometry and outputs a light curve. We’ve also been working with some new software called TAP (Transit Analysis Package) to fit planetary models to our transit data.

At night, however, I get to observe in Swarthmore’s wonderful new telescope. It is a 0.9m telescope with a 4K x 4K CCD. We installed a new filter wheel, and are in the process of making the system more automated by installing a weather detector that will shut down the dome in case of inclement weather. It has been very exciting to use the reduction code to produce light curves almost immediately after we have finished taking data, and to be able to see proof of planets around other stars!

I’ve been really enjoying living at Haverford- my first summer here- but working nearby. Philadelphia has been a really fun place to hang out: concerts, record hunting, food, and exploring in general. I also have to do research until after Haverford allows students to live on campus, so I’ll probably be living in Philly for a few weeks in August. A little annoying, but it should still be fun. This is my first summer research, and it has given me a great perspective on a possible future path for me. I’m still very unsure about what I want to do, but this has so far been a rewarding and exciting experience.

Summer Research at the American Museum of Natural History

Hi everyone, my name is Erin Boettcher and I am a senior astrophysics major at Haverford College. This summer, I have the great fortune of spending ten weeks doing research in the astrophysics department at the American Museum of Natural History in New York City. This National Science Foundation Research Experiences for Undergraduates program brings eight physical sciences students to the museum to do research alongside an advisor, get a taste for a new field of study, and get a chance to explore the city.  I am now almost five weeks into the program, and I can’t believe how fast the time has flown!

Both within and outside of the astrophysics department, the American Museum of Natural History is an amazing place to go to work every day.  My advisor, Emily Rice, studies low-mass stars, brown dwarfs, and exoplanets. Her current work focuses on fitting simulated spectra of brown dwarfs to observed spectra in order to deduce the objects’ physical properties such as chemical composition, temperature, and surface gravity.  My work so far has focused on evaluating how well best-fit simulated spectra for high resolution brown dwarf data fit low resolution data. High resolution data gives more “information” over a smaller wavelength range, while low resolution data gives less information over a wider wavelength range. Low resolution data is more widely available than high resolution data. Thus, determining the limitations of fitting simulated spectra to low resolution spectra is important to determining observing and fitting strategies. This research experience has allowed me to explore a new field of study, learn to program in Python, and have some fun at the same time!

Within the astrophysics department, the REU students are given guidance not only with regard to research skills but with regard to giving talks, attending conferences, applying to graduate school, and more. Each Friday, the astrophysics, geology, and biology departments hold a “wine and cheese” social for students and mentors. Each Friday is also a meeting of the APOD Club; at these meetings, the REU students give short talks inspired by images on the Astronomy Picture of the Day website. We have also been able to attend several talks given by visitors to the department, have been given tours of many of the museum’s exhibits, and are slowly seeing more and more of what the museum has to offer both in front of and behind the scenes. And of course, simply being at the museum means that we’re often in for a surprise, whether it’s a child’s birthday party taking a tour of the department, a camera crew filming an interview with Neil deGrasse Tyson , or the cast of Sesame Street filming an episode on the terrace outside.

In front of the Rose Center for Earth and Space and the Hayden Planetarium

In addition to loving my job at the museum, I have also found that I love being in the city. Though I’ve never considered myself to be a city girl, I may be slowly changing my mind! Between the free admission to all museums that we get with our museum IDs, the outdoor concerts, the street fairs, and more, it’s impossible to imagine not having something to do. Overall, I am reminded every day of how lucky I am to be here this summer. I hope everyone else doing research this summer feels lucky as well! I look forward to reading about it on Astronoblog!
