ATCA Observations of AT2018cow
Abstract
We have observed the position of AT2018cow (ATel #11727) with the Australia Telescope Compact Array (ATCA) on 2018-06-26 from 09:00-14:00 UT at central frequencies of 5.5 GHz, 9 GHz with a bandwidth of 2 GHz in each band, and 34 GHz with a bandwidth of 4 GHz. Due to maintenance, only four of six antennas were available, and only three antennas were used at 34 GHz. We detect a point source coincident with the location of AT2018cow (ATel #11727) and report preliminary flux densities of: < 0.18 mJy at 5.5 GHz (3-sigma upper limit); 0.46 mJy at 9 GHz; 5.6 mJy at 34 GHz. Analysis is ongoing and subsequent epochs are planned.
