Abstract:
The Australia Telescope Large Area Survey (ATLAS) has surveyed 7
square degrees of sky around the Chandra Deep Field South and the
European Large Area ISO Survey-South 1 fields at 1.4GHz. ATLAS aims
to reach a uniform sensitivity of 10uJy/beam rms over the
entire region with first data release currently reaching ∼30uJy/beam
rms. Here we present 466 new spectroscopic redshifts for radio sources
in ATLAS as part of our optical follow-up programme. Of the 466 radio
sources with new spectroscopic redshifts, 142 have star-forming
optical spectra, 282 show evidence for active galactic nuclei (AGN) in
their optical spectra, 10 have stellar spectra and 32 have spectra
revealing redshifts, but with insufficient features to classify.
Description:
Radio observations of ATLAS were carried out with the ATCA (Project ID
C1241). The ATCA was used in a variety of configurations (6A, 6B, 6C,
6D, 1.5D, 750A, 750B, 750D, EW367) to maximize uv coverage. ATLAS
observations were performed in mosaic mode with 40 pointings. The
radio data used in this paper are from DR1 (Norris et al. 2006, Cat.
J/AJ/132/2409; Middelberg et al. 2008, Cat. J/AJ/135/1276).

Note (1): from Norris et al. (2006, J/AJ/132/2409) and Middelberg et al. (2008,
J/AJ/135/1276), and are uncorrected for effects such as bandwidth smearing.
Note (2): the following classes are defined
(a question mark ? indicates an uncertain classification):
SF = star-forming galaxy (string, narrow emission lines including
Balmer series)
E = AGN with pure absorption-line spectra
E+OII = AGN with absorption lines, and low-ionisation emission-lines as
[OII] (λ=3726,3729Å)
AGNe = AGN with emission-line spectrum whose line rations are indicative of
AGN activity
AGNb = AGN with broad emission lines
gstar = G-type star
kstar = K-type star
mstar = M-type star
??? = unknown
