Program Summary:
We will perform a new GMOS galaxy redshift survey at z = 0.1 - 0.7 in the fields of 18 QSOs that have been observed with Hubble's Cosmic Origins Spectrograph. With thousands of new galaxy redshifts (a 50x gain over present surveys) we will fill the existing map of circumgalactic medium (CGM) gas out to 3Rvir to address the extent of metal transport and recycling, and the mechanisms of galaxy quenching in halos and large-scale environments, and the 2D structure of the CGM. This program will provide a uniquely rich dataset with a substantial legacy value.
