GCAV-Galaxy Clusters At VIRCAM

 

GCAV : Galaxy Clusters At VIRCAM

 

A VISTA ESO Public Survey

 

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.

Pilot Survey (P98):

 

The image show the stack of data from early observations carried out in P98 (Oct 2016-Dec 2016) for three of the four observed clusters (from left to right the central region of RCS2J2327, WHLJ2433, ACT CLJ0102, Ks band).
