CLASH: Magnified z > 6 High-Redshift Galaxies
Abstract
Gravitational lensing by massive galaxy clusters has been highlighted as an efficient approach to detect and study the properties of faint high-redshift galaxies. We present the status of our search for high-redshift (z> 6) galaxies after two years of ongoing CLASH (Cluster Lensing And Supernova survey with Hubble) observations of 20 galaxy clusters to date. Thanks to the magnification provided by the foreground clusters, some of these galaxy candidates are among the most distant ever seen. These observations are particularly useful for quantifying the rest-frame UV-continuum slopes of z> 5-8 galaxies, given the availability of a large number of WFC3/IR bands (F105W, F110W, F125W, F140W, and F160W). In this presentation, we discuss what we can learn about the UV slopes of the highest redshift (z> 6-8) galaxies from the CLASH program.
