Introducing Gourav Khullar

Gourav Khullar (@isskywalker, Pronouns: he/him) is a PhD Candidate at the University of Chicago, affiliated with the Dept. of Astronomy and Astrophysics, and the Kavli Institute of Cosmological Physics. An Indian national, he has been in Chicago since 2015, having moved to the US from the University of Cambridge with a masters degree in Astrophysics, and the Indian Institute of Technology, Delhi with a bachelors degree in Engineering Physics.
Gourav’s research focuses on the astrophysics of member galaxies of high-redshift galaxy clusters, which he studies via tools like optical-infrared spectroscopy and strong gravitational lensing. Gourav is part of the South Pole Telescope (SPT) Clusters collaboration, and is also affiliated with the Dark Energy Survey (DES). Counting himself as an observer and an analyst, Gourav is a frequent user of the Magellan Telescopes and the Cerro Tololo Inter-American Observatory (CTIO) in Chile for his research. His past work as an undergraduate and masters student includes an analysis of host galaxy properties in DES-discovered active galactic nuclei (AGN), understanding chemical enrichment in galaxy environments via simulations and observations, spectroscopic studies of Type Ib supernovae, and building stellar speckle interferometric apparatus in a laboratory that mimic adaptive optics systems on telescopes.
Outside astrophysics research, Gourav has also been a part of the Astrobites collaboration since 2015, both as a science communication writer-editor and an education researcher. Gourav also works on issues of social justice, having co-founded initiatives like the Diversity, Equity and Inclusion Journal Club (DEIJC) at UChicago, a platform that helps early-career astrophysicists create an equitable and inclusive local community through peer education. He is an organizer and officer with Graduate Students United – UChicago’s graduate worker union – which has been fighting for labor rights for graduate members of the UChicago community. On a light day, you would find Gourav reading non-fiction books, listening to Punjabi music, or at a movie theatre checking out the latest superhero flick!

Introducing Josephine Peters

Josephine Peters (@josieapeters) is a PhD student at the University of Oxford. She researches galaxy evolution with data from radio interferometers; the Very Large Array (VLA) and the Low-Frequency Array (LOFAR). She takes samples of hundreds of galaxies and looks at how their luminosity changes over the history of the Universe. Before her PhD, Josie did an MSc at the University of Manchester and a BSc in Maths at King’s College London. It was outreach in the form of a photography exhibition that inspired Josie to go into astronomy.

To share her love of astronomy (and hopefully inspire others as she was inspired), Josie presents videos on astronomy news, explains topics such as spacetime and quasars, and interviews other astronomers.

When other aspects of science grab her curiosity, Josie co-presents a new podcast called A Piece of String (@StringPodcast), that brings together comedians and scientific minds to answer the biggest of all questions, ever.

Beyond science, Josie spends her time drawing silly comics (@artartyeahart), performing improvised comedy with The Oxford Imps and singing loudly.

Introducing Adina Feinstein

Hi! My name is Adina Feinstein, and I just finished my undergraduate degree in astrophysics at Tufts University and will continue my education next year at U of Chicago. My research experiences range from galaxy evolution to correcting for gravitational lensing to aging stars and characterizing exoplanets. I hope to use my time on Astrotweeps to talk about my research, the graduate school application process, and offer advice to those who wish to pursue astronomy in the future. Outside of academia, I’m a bake-aholic, love to crochet, and enjoy writing the occasional short story!


Introducing Zach Pace

Zach Pace (@zpacefromspace) just finished the third year of his PhD program at the University of Wisconsin-Madison. A native of Buffalo, NY, Zach received a B.S. in Physics and a B.A. in Mathematics from the State University of New York at Buffalo in 2014. His research interests include galaxy evolution, chemical enrichment histories, and stellar populations. He works with data from the SDSS-IV MaNGA survey, an integral-field spectroscopic program that will produce spectral maps of 10,000 nearby galaxies by 2020. He is an avid, daily programmer, and an avowed machine-learning enthusiast.

Zach is also interested in scientific education and outreach. He regularly gives public presentations and telescope sessions at state parks around Wisconsin, through the Universe in the Park program. He served from 2014-2016 as Vice-Chair of Students for the Exploration and Development of Space, USA (SEDS-USA), an organization of nearly 50 college and university chapters dedicated to public engagement, career development, and science literacy. When not doing astronomy, Zach is often found reading, homebrewing, sailing, or playing pub quizzes (usually not simultaneously).

Reintroducing Ángel R. López-Sánchez

Dr. Ángel R. López-Sánchez is an astronomer and science communicator at the Australian Astronomical Observatory and the Department of Physics and Astronomy at the Macquarie University. He studies how gas is converted into stars in nearby galaxies and how this affects galaxy evolution. He also provides support for visiting astronomers to the Anglo-Australian Telescope (AAT, Siding Spring Observatory, NSW). Dr. López-Sánchez is passionate science communicator who continuously gives talks and public lectures, writes popular science articles and organizes stargazing activities. He is very active in social media, his Twitter feed is @El_Lobo_Rayado.

Reintroducing Chris Lintott

Chris Lintott is a professor of astrophysics at the University of Oxford, where he leads the team of people responsible for the collection of citizen science projects. Volunteers have used the Zooniverse to classify galaxies, discover planets (and perhaps but probably not an alien megastructure), catch supernovae and do a lot of non-astronomical things too. His own research is on galaxy evolution and formation, mostly using data from Galaxy Zoo to think about what changes star formation in galaxies. His background is a little closer to home, having completed a PhD at University College London mostly on the chemistry of star formation; he’s a big fan of triply-deuterated ammonia but likes sulphur compounds the best.

Chris is best known (in the UK at least) as the co-presenter of the BBC long-running Sky at Night program, a monthly look at the worlds of astronomy and astrophysics. This has taken him to all sorts of places, including the control room for ESA’s Rosetta mission which ends this week. He also once got the age of the Universe wrong on camera by a factor of a million. Away from research, Chris answers email. Away from email, he can be found cooking, watching theatre or opera or shouting loudly at the Chicago Fire and Torquay United. He also plays real tennis, which is far superior to the young upstart lawn tennis.

Most other days, you can find Chris on twitter at @chrislintott
