Abstract:
We present the results of spectroscopy using HYDRA on the WIYN 3.5m
telescope of objects in the deep SWIRE radio field. The goal of the
project was to determine spectroscopic redshifts for as many of the
brighter objects in the field as possible, especially those detected
in the radio and at 24um. These redshifts are primarily being used in
studies of galaxy evolution and the connection of that evolution to
active galactic nuclei and star formation. Redshifts measured for 365
individual objects are reported. The redshifts range from 0.03 to 2.5,
mostly with z<0.9. The sources were selected to be within the WIYN
HYDRA field of approximately 30' in radius from the center of the
SWIRE deep field, 10:46:00, +59:01:00 (J2000). Optical sources
for spectroscopic observation were selected from an r-band image of
the field. A priority list of spectroscopic targets was established in
the following order: 20cm detections, 24m detections, galaxies with
r<20 and the balance made up of fainter galaxies in the field. We
provide a table listing the galaxy positions, measured redshift and
error, and note any emission lines that were visible in the spectrum.
In practice, almost all the galaxies with r<19 were observed including
all of the radio sources and most of the 24um sources with r<20 and a
sample of radio sources which had fainter optical counterparts on the
r-band image.
Description:
The observations were made on 2004 February 11-15 using the HYDRA
fiber spectrograph on the WIYN 3.5m telescope at KPNO.
