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.
