The 100 Strongest Radio Point Sources in the Field of the Large Magellanic Cloud at 1.4 GHz
We present the 100 strongest 1.4~GHz point sources from a new mosaicimage in the direction of the Large Magellanic Cloud (LMC). The observationsmaking up the mosaic were made using Australia Telescope Compact Array (ATCA)over a ten year period and were combined with Parkes single dish data at 1.4 GH...

| description | We present the 100 strongest 1.4~GHz point sources from a new mosaicimage in the direction of the Large Magellanic Cloud (LMC). The observationsmaking up the mosaic were made using Australia Telescope Compact Array (ATCA)over a ten year period and were combined with Parkes single dish data at 1.4 GHz to complete the image for short spacing. An initial list of co-identifications within 10arcsec at 0.843, 4.8 and 8.6 GHz consisted of 2682 sources. Elimination of extended objects and artifact noise allowed the creation of a refined list containing 1988 point sources. Most of these are presumed to be background objects seen through the LMC; a small portion may represent compact HII regions, young SNRs and radio planetary nebulae. For the 1988 point sources we find a preliminary average spectral index ($alpha$) of -0.53 and present a 1.4 GHz image showing source locationin the direction of the LMC. |
