Tell me a little about yourself.

I am currently a rising senior at Grinnell College in Iowa, majoring in Physics. Though I grew up in North Carolina, I’ve lived all over the country at various points. I had the unique opportunity to go to a dual enrollment high school, where you can take college classes at a local college in your junior and senior years. Because of this, I was able to take a unique astronomy class using the college observatory quite early on. I also got to use the college darkroom and spent a lot of time experimenting in there.

Other hobbies I’ve developed in the past year or so include cooking, as we’ve all been home so much recently. I’ve been doing school fully online for the last year but living with a bunch of friends and cooking with them. My favorite cuisine is Indian, and I’ve been learning to make it since there isn’t a good place to get it within a 30 minute drive.

How did you get interested in astronomy?

I got into astronomy because of my interest in photography. I enjoyed using the darkroom and taking photography classes, a lot of it just for fun. I also had been taking a lot of my physics classes, and had access to an observatory. When I saw there was an observational astronomy course that I could take and realized telescopes are just different types of lenses, I was excited to try it out. It was an extension of my interest in physics and photography. My summer research advisor at DAWN is also really into photography, which is a nice connection.

What is your favorite part about DAWN?

I would say that it is really nice to be a part of an institute that is very focused on a specific era in the universe. It feels like we are all trying to answer some of the same questions at the same time and in the same (virtual) place. In that sense it feels different from a university where there is a much wider field of study. It is really cool to see how everyone’s work interconnects by going to the Cake Talks and other larger DAWN meetings.

What motivated you to apply to an international REU?

At the time that I applied (which was over two years ago given the cancellation in 2020), half of my class was applying to study abroad programs (something like 50% of students study abroad in their third year to get the "Grinnell experience”). I knew I wanted to study abroad and go into astronomy, but there were very few opportunities that would allow me to do both. I was torn, because while I was willing to take a semester away from astronomy, I didn’t want to, as it was something I enjoyed studying. I knew that a lot of astronomy research is done internationally, so this program really seemed perfect to spend my summer abroad and see how international collaborations work and perform research relevant to the field I want to go into. Some of those things didn’t pan out in that I am still in the US due to the pandemic, but my experience has definitely given me a better understanding about how international collaborations work.

How has the pandemic impacted your life?

Grinnell sent us home in March 2020 and I spent the summer back home in North Carolina. However, I was able to make it work to live with some friends for the fall semester. Because travel was still somewhat rare at that point, we were able to find discounts on housing and we ended up renting a big house in the mountains of Northern Utah for the semester. We did our online classes from there and got to live together, cook great meals, and explore the area. This was an experience that I never would have had if not for the pandemic, so that was positive outcome. I’ve had a lot of weird adventures that would never have have happened if classes were not remote. On the whole, the pandemic has had a lot of silver linings despite also being a very difficult and strange time.

If you could have any superpower what would it be?

Flying—it seems like so much fun! To be clear, I don’t want to go sky diving—that sounds too dangerous—but if I could fly and have total control and no reason to worry, that would be very cool.

Tell me about your summer research project.

Some recent observations have found that, at early times in the universe, there were large halos of gas around galaxies that cannot be explained entirely by star formation. There are theories on their origin, including possible evidence of ongoing or previously outflowing neutral gas. I’m working with data from ALMA studying a single strong gravitationally lensed galaxy at a redshift of 7 to look at the distribution of the gas in this galaxy. In particular, we are looking for this extended halo of gas and for any signatures of outflowing gas. Earlier results are based on stacking of data from many galaxies, but our study would be one of the first times this has been shown for an individual galaxy.

Where is the first place you want to visit when we finally get you to Copenhagen?

This is a tough question because I know very little about Copenhagen—but I will probably start with a visit to whatever the internet tells me is the best coffee shop in Copenhagen.

Tell me a little about yourself.

I am a rising Senior at Columbia University in NYC (I love NYC!) and originally from Massachusetts. I went to college with the intention of studying astrophysics but I really struggled with the large, impersonal intro physics courses at first. Last summer I was supposed to stay in the city to do research, but the program got cancelled. Instead I coded an entire summer from my parent’s basement (the only place with A/C!) - that really scarred my first research experience, unfortunately. But so far this summer has been a totally new experience and I’m really enjoying it. Living with friends in the city instead of at home has helped to change my expectations and I also feeling lucky that I have an opportunity to do research despite the pandemic. My perspective has really changed from last year.

Beyond astronomy, I have a few really obscure hobbies. First, I am in a Scottish fiddle band (we’ve recorded two albums!). I also speak Chinese and sometimes do subtitles and translation. The three things in life I care most about are astro, languages, and music. In terms of personal development, I believe it is important to have hobbies not related to work. My ultimate goal is to work in a country that doesn’t speak English and be able to speak the language fluently.

How did you get interested in astronomy?

In elementary school, I was always the “math kid” and I have also always really liked space. I don’t ever remember the conscious decision to study astrophysics in college, it just made sense. My first direct experience with physics was in high school. This was also one of the first courses to really challenge me, which I found equally rewarding.

What is your favorite part about DAWN?

I really like how the people at DAWN seem to know what everyone else is up to. The research community seems to be really close knit. I haven’t yet had a chance to experience what makes DAWN specifically “DAWN” or feel the character of the place yet but I am looking forward to getting to the know the center better moving forward.

What motivated you to apply to an international REU?

I would like to move out of the US and attend graduate school abroad. It was natural to build connections and check out the character of research at institutes outside of the US. My mentor this summer at DAWN did her undergraduate and masters in Italy and then a PhD in Munich, Germany. This program gives me a rare opportunity to learn more about graduate school abroad, an experience that I wouldn’t get if I attended a US-based summer research program.

How has the pandemic impacted your life?

On a personal level, I haven’t experienced a lot of loss and so I feel lucky. But it has changed the way I think about what I want out of my own future. I had spent my entire time in secondary school wanting to get out of Massachusetts. I have truly loved living in the city and so when I got sent home due to the pandemic I felt directionless. It was hard to find motivation to do research, and research itself also felt out of reach at that point. Many of my close friends went home and I still haven’t seen them. I experienced a lot of isolation and was forced to live somewhere I didn’t want to be - that was hard. And online classes were terrible. The worst thing ever. Online classes in the pandemic have fundamentally changed how I go about doing school work. I am more focused on learning material I care about and not destroying myself to finish everything. It has helped change my perspective about what really matters.

If you could have any superpower what would it be?

Teleportation - I want to go everywhere and I don’t like long plane rides. I would go to Brazil first. I have to travel to Boston every other weekend for my band and it is a lot of time and expensive. Teleportation would really help!

Tell me about your summer research project.

For my summer research project, I am looking at two different galaxy kinematic fitting models that are similar but one uses Markov chain Monte Carlo methods while the other does not. I am fitting data cubes to models of the galaxies — so far I’ve created 24 different models with different parameters! I am comparing the two different model packages and the goal is to apply it to real data eventually.

Where is the first place you want to visit when we finally get you to Copenhagen?

I’ve already done the tourist stuff in a previous visit to Copenhagen, so what I really want to see is the Cosmic Dawn Center itself to build a more personal connection to the city. And then we can all go out together to an open air cafe. My absolute favorite thing about European cities is the outdoor dining. Since Covid, we know have this all over NYC which has been a nice silver lining.

Meet the DAWN-IRES Senior Scholars: Rebecca Larson

Tell me a little about yourself.

I am a fifth-year Ph.D. candidate in the Department of Astronomy at UT Austin, and I am originally from California. I enlisted in the military when I was 17 years old to become an Arabic translator working for the National Security Agency. My goal was to go to college and one of the main benefits of my assignment in the Air Force was that I could take night classes. I was working towards a business and studio art degree, but I also took some computer science classes. I feel that often this artistic side of me comes out in developing my science posters and plots; I am quite particular about color schemes! Marketing, promotion, and a fundamental understanding of the customer are also important in the sciences — when you propose for something, you are ultimately selling your science and ideas to a reviewer, and it helps to view this process through that lens. Sometimes I feel like I wasted a lot of time on taking classes for these degrees that did not translate directly to Astronomy, but I recognize the benefits and skills I gained, like helping me to break stage fright among other things.

How did you get interested in astronomy?

After the military, I went to San Jose State full time. However, when my family moved to Austin, I followed and tried to transfer to UT Austin. Unfortunately, the Business School wouldn’t accept my request to transfer because I had too many credit hours (I ended up graduating with 226 credits, 100 more credits than you need for a degree). I eventually got accepted into UT Austin as an undeclared major, but I could only pick majors in the natural sciences or liberal arts, and the list they gave me was alphabetical. I liked space and science fiction, so I picked Astronomy on a whim, and I found myself starting over in a new degree taking introductory physics courses and failing miserably! I tried to find some purpose in astronomy by starting a research project with a professor at UT Austin. I am so grateful for the time that he invested in me and during that project that I ended up making a discovery that no other human has done. I realized I wanted to do this forever; it was truly the coolest thing I have ever experienced. I continued to struggle with my classes, and I ran out of funding from the military, but I got scholarships to pay for a third year to finish my degree so that I could apply for graduate school. Had this professor not taken a chance on me, I would have given up and not be here today; I am forever grateful to him. While Arabic came very naturally to me, physics does not - it doesn’t click for me, and I struggle with it to this day. But I recognize I can love doing something and not be the best at it. Ultimately being happy is much more important.

What is your favorite part about Dawn?

I like the concept of a center of research excellence. I have taken advantage of opportunities to work at these types of places before and I was interested in seeing what an institute such as this would be like in another country. I am excited about the research atmosphere that Dawn provides. Having a pure research-driven environment is exciting to me.

What motivated you to apply to an international REU?

My main motivation came from thinking about where I want to apply for postdocs. I have had opportunities to live in different places that I have not taken in my life, and so it felt like the right way to approach this next stage of my career by spending some time in a place I might want to move to. It will be a different culture for both work and life and I think it is important to experience this firsthand. It is better for me as a human, and for astronomy as a whole, for us to be more international.

How has the pandemic impacted your life?

I want to start off by saying I am very lucky and privileged that the impact that the pandemic has had on me is only that of mental stress as I haven’t experienced great personal hardship or loss. I am so grateful that the main impact for me was only canceled internships and travel. It sucks to have a well-planned out summer of talks, internships, travel, and conferences that all got put on hold or canceled. This has been depressing and especially difficult to watch those opportunities all disappear, but I feel grateful to have my family nearby.

If you could have any superpower, what would it be?

Teleportation - traveling is such a pain! I don’t like driving and I have friends all over the place from different parts of my life (astronomy, military, etc) and travel times are such a barrier to seeing friends. Wouldn’t it be great to pop in for a lunch visit? It would take all the hassles out, leaving more time for the important stuff.

Tell me about your Ph.D. project.

I study galaxies from the very beginning of the universe to understand how they, and the Universe itself, evolve into the one we live in today. We search through the dense fog of the early universe to discover these sites of intense star formation in galaxies that are lighting up the early universe. I use ground and space-based telescopes to push our current technological capabilities to see as far back in time as possible. I am super excited (and nervous) about the upcoming James Webb Space Telescope as it will usher into a new era of discovery!

Where is the first place you want to visit when we finally get you to Copenhagen?

I want to hop on a bicycle and go to visit Mikkeller and the food market next door…. I can’t wait!

Anything else that you want to share?

I feel a big part of our job is to increase humanity's knowledge of our place in the universe and how we got here and the effort to communicate science to the rest of humanity is an important aspect of being an astronomer. To that end, I am involved with Astronomy on Tab in Austin and spend time talking to people in daily life about space and science. Outreach can be a very powerful tool because astronomy is an easy-access science, every person can go outside and look up at the sky and be a part of what we do. It is important for us to continue to share what we are learning with the rest of the world in as much of a capacity as we are able.
