Australia Telescope Compact Array observations of Fermi unassociated
  sources
  We report results of the first phase of observations with the Australia
Telescope Compact Array (ATCA) at 5 and 9 GHz of the fields around 411
gamma-ray sources with declinations < +10 deg detected by Fermi but marked as
unassociated in the 2FGL catalogue. We have detected 424 sources with flux
densities in a range of 2 mJy to 6 Jy that lie within the 99 per cent
localisation uncertainty of 283 gamma-ray sources. Of these, 146 objects were
detected in both the 5 and 9 GHz bands. We found 84 sources in our sample with
a spectral index flatter than -0.5. The majority of detected sources are weaker
than 100 mJy and for this reason were not found in previous surveys.
Approximately 1/3 of our sample, 128 objects, have the probability of being
associated by more than 10 times than the probability of being a background
source found in the vicinity of a gamma-ray object by chance. We present the
catalogue of positions of these sources, estimates of their flux densities and
spectral indices where available.
