Cluster Lensing And Supernova survey with Hubble (CLASH): A Magnified View of the High-Redshift Universe
Abstract
The Cluster Lensing And Supernova survey with Hubble (CLASH) is a 524-orbit multi-cycle treasury program to observe 25 galaxy clusters each in 16 broadband filters with WFC3 and ACS. One of the many goals of CLASH is the detection and characterization of z > 6.5 galaxies. Gravitational lensing by massive galaxy clusters can considerably amplify both the brightness and size of high-redshift sources and improves the search efficiency for relatively bright high-redshift galaxies. We will present a new sample of high-redshift galaxy candidates at z > 6.5 and their properties from our ongoing cluster observations.
