Mario Jurić (@ is a professor of Astronomy at the University of Washington (@uwastronomy) & eScience Institute Fellow (at @uwescience). He’s interested in astronomical ‘Big Data’: developing and applying data science methods that let astrophysicists use large data sets to answer research questions. Two experiments he’s involved with are the Large Synoptic Survey Telescope (LSST), and the Zwicky Transient Facility (ZTF). Loves Python, prefers tabs, and thinks bash scripting is fun
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 excited to be hosting week two (19-25 Jan 2014) of Astrotweeps! I am an astrophysicist who works on the Sloan Digital Sky Survey (SDSS) at Ohio State University. SDSS was responsible for producing the largest color image of the sky ever made – a trillion pixels that would require half a million HDTVs to display. But that’s old news – the current phase of the survey has collected over a million spectra of stars and galaxies. A spectrum is a measurement where the light is split into different wavelengths, like that you would see through a prism. My current research interest is using this data to learn how galaxies evolve over time and even the histories of individual galaxies. I am also interested in the data science aspect of research; how we as astronomers can analyze and do science with far more data than we’ve ever had access to. It’s a good problem to have, but not a solved one. I’m also a contributor to the Astropy project. I am also interested in public outreach and run a chapter of Astronomy On Tap. In a prior life, I worked on a dark matter experiment called DRIFT, located 1.1km underground in a working mine that is a stone’s throw from where Dracula landed in England. I also curl.
I look forward to your questions on galaxy evolution, dark matter, curling, or anything else you’d like to hear about! Send questions to @astrotweeps or as a comment on this blog post. After this week, you can follow me on Twitter at @demitrimuna and @scicoder.
