Abstract:
We present a radio survey carried out with the Australia Telescope
Compact Array. A motivation for the survey was to make a complete
inventory of the diffuse emission components as a step towards a study
of the cosmic evolution in radio source structure and the contribution
from radio-mode feedback on galaxy evolution. The Australia Telescope
Low-Brightness Survey (ATLBS) at 1388MHz covers 8.42deg2 of the sky
in an observing mode designed to yield images with exceptional surface
brightness sensitivity and low confusion. The survey was carried out
in two adjacent regions on the sky centred at 00:35:00-67:00:00 and
00:59:17=-67:00:00 (J2000.0). The ATLBS radio images, made with
0.08mJy/beam rms noise and 50arcsec beam, detect a total of 1094
sources with peak flux exceeding 0.4mJy/beam. The ATLBS source counts
were corrected for blending, noise bias, resolution and primary beam
attenuation; the normalized differential source counts are consistent
with no upturn down to 0.6mJy.
