Abstract:
The initial Phoenix Deep Survey (PDS) observations with the Australia
Telescope Compact Array have been supplemented by additional 1.4 GHz
observations over the past few years. Here we present details of the
construction of a new mosaic image covering an area of 4.56 deg2, an
investigation of the reliability of the source measurements, and the
1.4 GHz source counts for the compiled radio catalog. The mosaic
achieves a 1-sigma rms noise of 12 microJy at its most sensitive, and
a homogeneous radio-selected catalog of over 2000 sources reaching
flux densities as faint as 60 microJy has been compiled. The source
parameter measurements are found to be consistent with the expected
uncertainties from the image noise levels and the Gaussian source
fitting procedure. A radio-selected sample avoids the complications
of obscuration associated with optically selected samples, and by
utilizing complementary PDS observations, including multicolor
optical, near-infrared, and spectroscopic data, this radio catalog
will be used in a detailed investigation of the evolution in star
formation spanning the redshift range 0 < z < 1. The homogeneity of
the catalog ensures a consistent picture of galaxy evolution can be
developed over the full cosmologically significant redshift range of
interest.
Description:
The Phoenix Deep Survey is a multiwavelength survey of a region a
little over 2degrees diameter in the southern constellation Phoenix.
The Phoenix Deep Field 1.4GHz catalog results from observations made
with the Australia Telescope Compact Array.
The catalogue contains 2148 sources, and is the merge of the threshold
catalogue from the trimmed mosaic image (2090 sources) and the deep
catalogue of the 33'x33' region centered on the most sensitive portion
of the mosaic (491 sources).
