High Redshift Galaxies, Supernovae, and Cluster Dark Matter with the CLASH Project

I will discuss a few of the results from the Hubble MultiCycle Treasury Project, Cluster Lensing and Supernova (with) HST (CLASH). These data, covering 25 clusters with 16 HST filters from the observer frame ultraviolet to the near infrared, are public in the HST archive, and are a rich source of scientific projects for our team and the astronomical community. We have discovered two of the most distant galaxies known in the universe and we are putting interesting constraints on the distribution of dark matter using lensing techniques in massive clusters of galaxies, using the same data. I will also show a few of the supernovae detections, as well as a few very interesting cluster galaxies. The sample, to be completely observed by mid-summer, will yield interesting constraints on non-thermal pressure support in intracluster gas as we compare cluster masses derived from lensing and from the X-rays.
