Galaxy Evolution from the Caltech Faint Galaxy Redshift Survey

Dr. Michael Pahre, CfA

Abstract

The Caltech Faint Galaxy Redshift Survey (CFGRS) comprises a series of studies of the evolutionary history of field galaxies at intermediate redshifts. The dataset includes imaging from the U-band to the K-band, and redshifts obtained at the Keck Telescopes, for several "pencil beam" survey areas. This talk will introduce the survey and present some of the main results: (1) the "number" problem and proposed origin(s) for the faint galaxy counts; (2) evolution of the comoving star formation rate to z=1, as traced by the [O II] line; (3) strong clustering in redshift space at intermediate redshifts; (4) the correspondence of clustering and spectrophotometric properties of the field galaxies; and (5) the possible nature of extremely red objects in the field.
