Caltech Faint Galaxy Redshift Survey. X. A Redshift Survey in the Region of the Hubble Deep Field North

A redshift survey has been carried out in the region of the Hubble Deep FieldNorth using the Low Resolution Imaging Spectrograph at the Keck Observatory.The resulting redshift catalog, which contains 671 entries, is a compendium ofour own data together with published LRIS/Keck data. It is more than 92%complete for objects, irrespective of morphology, to $R = 24$ mag in the HDFitself and to $R = 23$ mag in the Flanking Fields within a diameter of 8 arcmincentered on the HDF, an unusually high completion for a magnitude limitedsurvey performed with a large telescope. A median redshift $z = 1.0$ is reachedat $R \sim 23.8$. Strong peaks in the redshift distribution, which arise when a group or poorcluster of galaxies intersect the area surveyed, can be identified to $z \sim1.2$ in this dataset. More than 68% of the galaxies are members of theseredshift peaks. In a few cases, closely spaced peaks in $z$ can be resolvedinto separate groups of galaxies that can be distinguished in both velocity andlocation on the sky. The radial separation of these peaks in the pencil-beam survey is consistentwith a characteristic length scale for the their separation of $\approx$70 Mpcin our adopted cosmology ($h = 0.6, \Omega_M = 0.3$, $\Lambda = 0$). Stronggalaxy clustering is in evidence at all epochs back to $z \le 1.1$. (abstractabridged)Comment: Accepted to the ApJ.
