HST CLASH: Clusters, High-z Galaxies, Supernovae
Presented by Megan Donahue
Michigan State University

Thursday, March 21, 2013
4:00 P.M. in 169-336

Abstract
I will discuss a few of the science questions being addressed through the HST Multi-Cycle Treasury (MCT) Program to study 25 massive and distant clusters of galaxies and their gravitationally-lensed preview of the very high redshift universe. The dataset being collected through this program is unprecedented in its breadth. Very rarely have we been privileged to view clusters from the ultraviolet through to the infrared. I will describe some of the recent results from the Cluster Lensing And Supernova survey with Hubble (CLASH) science team, including the discovery of some of the most distant galaxy candidates and supernovae, and I will highlight on-going work at Michigan State on the X-ray emission from the hot gas in the clusters and the brightest cluster galaxies.
