and COS-Halos

 
 

I am an astronomer at the Space Telescope Science Institute (STScI). My research concerns the formation and evolution of stars and galaxies over cosmic time. I am now pursuing some more specific questions:


  1. What were the first stars, and how and when did they yield to Pop II?


  1. How can we use data from high and low redshift to understand the earliest galaxies?


  1. How does gas arrange itself in galaxy halos, and what role does halo gas play in galaxy evolution?


My work bounces back and forth between theory and observing, sometimes in the same day, or even the same hour. For fun, my colleagues and I are building of one of these:








If you’re really nice, maybe we’ll let you use it.
