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.
