Cosmic Evolution in the Australia Telescope Large Area Survey (ATLAS)

Thursday August 30, 2012
2:00 pm

 Presenter:  Minnie Mao (NRAO)
 Series:  Institute for Astrophysics Seminar Series
 Abstract:  The Australia Telescope Large Area Survey (ATLAS) observes seven square degrees of sky down to 10 microJanskys at 1.4 GHz using the Australia Telescope Compact Array. The survey covers two fields to minimise cosmic variance; the Chandra Deep Field South (CDFS) and the European Large Area ISO Survey - S1 (ELAIS). Using spectroscopic redshifts we obtained from the Anglo-Australian Telescope, we have studied the radio luminosity function for ATLAS sources. We have identified and analysed wide-angle tailed galaxies in ATLAS and discovered a ~12 Mpc large-scale structure in ELAIS at z~0.2. Using deep far-infrared data from the FIDEL project we were able to study the far-infrared radio correlation in the eCDFS and we found no evidence for evolution out to redshifts of ~3.
