ASKAP POSSUM

The Rapid ASKAP Continuum Survey (RACS) has imaged the entire Southern radio sky from 744-1032 MHz, and will be extended to also cover 1296-1440 and 1600-1800 MHz. A total intensity catalog produced from the low-frequency RACS observations (published here) contains entries for about 2.1 million sources, making it the largest radio continuum survey in the Southern hemisphere to date. The POSSUM team is delivering linear polarization products from the RACS data, through the SPICE-RACS (Spectra and Polarization In Cutouts of Extragalactic Sources from RACS) project (track developments here)... The POSSUM survey requires exquisite full-polarization performance from ASKAP's novel widefield Phased Array Feed (PAF) system. Our team is directly involved in characterising and correcting instrumental errors that can mask the astrophysical signals of interest. POSSUM members are also instrumental in developing new, efficient algorithms for extracting detailed polarization characteristics from..
