Title: A Redshift Survey of Radio-selected Galaxies in the SIRTF First Look Survey

Abstract: We propose to obtain (and make public) WIYN/HYDRA redshifts of 290 Sloan-selected galaxies from the planned SIRTF First Look Survey (FLS) region which have been detected in a deep VLA 20cm radio survey. Almost all the galaxies detected by the VLA are expected to be detected by SIRTF. Because of the unprecedented sensitivity and high angular resolution of SIRTF, the FLS is intended to provide astronomers with an early glimpse of unexplored observational parameter space. Having redshifts available for likely SIRTF sources in advance of the survey will significantly multiply the usefulness of the FLS. Accurate redshifts and spectroscopic classifications will allow a statistically significant sample of galaxies to be used to: 1) probe possible changes in the radio and IR luminosity functions and star-formation-rate density over the last 5 Gyrs in the history of the universe, 2) help determine the AGN/starburst fraction and AGN/SB classification strategies early in the mission in preparation for deeper surveys, and 3) explore AGN/Starburst environmental effects in groups/clusters over large-scales not possible with the smaller targeted SIRTF fields. Because of the depth of the VLA survey, the observations have intrinsic merit, but they are especially timely given the planned launch-date for SIRTF (Jan 2003).
