James Guillochon is currently a postdoc at the Institute for Theory and Computation in the Harvard astronomy department. He studies the tidal disruptions of stars by supermassive black holes and supernovae, runs hydrodynamical simulations to figure out their physics, and compares model predictions to observed data. He maintains Vox Charta and the Open Astronomy Catalogs (AKA Astrocats)
Abigail Stevens is a PhD candidate at the Anton Pannekoek Institute for Astronomy at the University of Amsterdam in the Netherlands. She researches X-ray spectral variability from compact objects (stellar-mass black holes and neutron stars) in order to understand the extreme physics in strong gravitational fields, and is very excited for NICER to be launched in a few months. Abbie is also a “pythonomer” and is involved in the open science community. Previously, Abbie did her MSc at the University of Alberta in Edmonton, Alberta, Canada, and her BA at Bard College in Annandale-on-Hudson, New York, USA. In addition to her astronomy research, she enjoys tea, interior design, memes, reading blogs, watching tv, and exploring new places.
Anna Weigel (@annakweigel) is a third year Ph.D. student at ETH Zurich in Switzerland. Her research focuses on the connection between galaxies and their black holes. Specifically she studies if and how active black holes might be shutting down star formation in their host galaxies. Instead of closely examining single objects, Anna is combining phenomenological and statistical approaches. This means looking for trends and correlations in the local galaxy population as a whole.
Anna received her B.S. in physics from the Karlsruhe Institute of Technology in Germany and then moved to Switzerland for her M.Sc. in physics at ETH. Before starting her Ph.D., she spent three months at the Swinburne Centre for Astrophysics and Supercomputing in beautiful Melbourne. Anna enjoys teaching, which is part of her Ph.D. student duties, and doing outreach. For example, building galaxies with kids has taught her that 7-year olds and glitter glue do not mix well. From time to time Anna also likes to visualise science in the form of delicious cakes.
I am currently a part time lecturer at the University of Western Sydney in Australia as well as the Information Support Officer for the International Telescope Office at the Australian Astronomical Observatory. I also do public astronomy tours as a guide at Sydney Observatory. All this is motivated by my passion for astronomy, physics and exploration. This passion has led me through a bachelor’s in Astronomy and Physics (with minors in Optical Engineering and Planetary Sciences) at the University of Arizona in Tucson, Arizona, a research program at the Max-Plank Institute, a masters program in Astrophysics from the University of Amsterdam and my PhD studies at Macquarie University. These studies allowed me to participate in research on both optical spectra, abundances, and kinematics as well as lithographic construction of photonic crystals for use in submillimeter and radio astronomy; planetary sciences and engineering pnCCDs for X-ray astronomy.
I am very interested in observational astronomy as well as the theory behind it, and, yes, even the data management. I participated in the project ASTRO in Tucson, Arizona where we used both theory and observations to involve school teachers and their classes in astronomical research. I also enjoy giving public talks and participating in public observing or ‘star parties’ where the knowledge that I have gained can be shared with the larger community. I find the study of stars and binary stars in late stages of stellar evolution very exciting. I also enjoy planetary sciences, Archaeo-astronomy, and space sciences (in particular Mars satelite imagery via THEMIS) and exoplanet studies, although so far these have been mostly investigated in my free time. For my current science research I am primarily interested in the study of spectral features and the use of ground-based as well as space-based observatories to pursue the realm of Galactic Archaeology and Stellar Streamers in our own local group in particular the Sagittarius dwarf galaxy and its associated stream. Most recently I submitted conference proceedings for the recent ADASS meeting in Sydney on data selection techniques and a paper on the interesting black hole binary LMC X-1 from the perspective of the O star.
