Abstract

We present a catalog of 30 quasars (QSOs) and their spectra, in the square degree of sky centered on the northern Hubble Deep Field. These QSOs were selected by multicolor photometry and subsequently confirmed with spectroscopy. They range in magnitude from 17.6 < B < 21.0 and in redshift from 0.44 < z < 2.98. We also include in the catalog an active galactic nucleus with redshift z = 0.135. Together, these objects comprise a new grid of absorption probes that can be used to study the correlation between luminous galaxies, nonluminous halos, and Lyα absorbers along the line of sight toward the Hubble Deep Field.
