Australia telescope compact array observations of Fermi unassociated sources.


Abstract (from CDS):

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 γ-ray sources with declinations <+10° detected by Fermi but marked as unassociated in the Fermi Large Area Telescope 2-Year Source Catalog (2FGL). We have detected 424 sources with flux densities in the range 2-6 Jy that lie within the 99 per cent localization uncertainty of 283 γ-ray sources. Of these, 146 objects were detected in both 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 one third of our sample, 128 objects, have a probability of being associated more than 10 times greater than the probability of being a background source found in the vicinity of a γ-ray object by chance. We present the catalogue of positions of these sources, estimates of their flux densities and spectral indices where available.
