Astronomy Colloquium
"Evolution of Galaxy Populations in the Most Distant Galaxy Clusters"
Time: 3:30 pm
Place: 4421 Sterling Hall
Speaker: Mark Brodwin, University of Missouri- Kansas City
Abstract: I will describe the emerging evidence for an epoch of significant growth of cluster galaxies at z ~ 1.5, about 10 billion years in the past. This evidence rules out the (overly) simplistic galaxy formation models that seem to fit the data at later times (ie. at z < 1). New measurements of rapid evolution in a number of critical probes of the growth of cluster galaxies aEuro" including a census of their stars, the colors of those stars, and the rates of star formation, mergers and black hole activity aEuro" all suggest the z ~ 1.5 era is a very active one in the formation and assembly of massive cluster galaxies.
