The Caltech Deep Redshift Survey (CDRS) has been working in two fields. More than 1000 redshifts for faint field galaxies in these two fields are in hand. Our discovery of strong redshift clustering at high z is now amply confirmed by the large data set in hand. Many redshift peaks, with a typical, but non-periodic, spacing of ≈100 h^(-1) Mpc, are seen in the HDF data. We have carried out a preliminary determination of the luminosity function for galaxies, as well as an analysis of the star formation rate as a function of time. The two point correlation function for galaxies has also been derived. The spatial analysis is directly calculated using the statistics of pairs. A byproduct of this analysis is the measurement of the deviation from smooth Hubble flow (≈300 km/sec in the rest frame) at z ≈ 0.6. The spectral analysis is in a very preliminary state. Thus far we have established that the emission line ratios for our sample indicate photoionization by starlight and do not provide any evidence for a contribution by a harder ionizing flux (i.e. AGNs).

Keck Observatory, which is operated jointly by the California Institute of Technology and the University of California. The entire Keck/1RIS user community owes a huge debt to Jerry Nelson, Gerry Smith, Bev Oke, and many other people who have worked to make the Keck Telescope and 1RIS a reality. We are grateful to the W. M. Keck Foundation, and particularly its late president, Howard Keck, for the vision to fund the construction of the W. M. Keck Observatory.
