GCAV : Galaxy Clusters At VIRCAM
A VISTA ESO Public Survey (198.A-2008%, P.I. M. Nonino)
GCAV is a second generation ESO Public VISTA Survey aimed at observing 20 Clusters of Galaxies covering in total ~30 deg2 in Y, J and Ks bands
Science Goals:
Galaxy clusters and filaments host a rich variety of galaxy types and environments and are ideal testbeds in which to study the role of nature versus nurture in galaxy evolution. VIRCAM @ VISTA Field of View will allow to sample a wide dynamic range in density from the field to overdense regions in clusters central regions.
The proposed depths will also allow e.g. search for high-redshift QSO and cool L,T dwarfs; to study the infrared galactic star counts and colours, and compare them with theoretical predictions.
