ASKAP Commissioning Update
November's ASKAP Commissioning Update is now available. In addition to news about the ASKAP pilot surveys, Rapid ASKAP Continuum Survey (RACS), eROSITA collaboration, and ASKAP-X project, the Update contained a report on the most recent efforts to find a counterpart to a LIGO gravitational wave event. The image above was made following the LIGO event S190814bv. It is a 10-hour integration at a centre frequency of 944 MHz with a bandwidth of 288 MHz. The field contains NGC 253, visible as a bright extended source slightly to the right of centre. Initial ASKAP observations detected a few variable radio sources inside the uncertainty region that have since been classified as active galactic nuclei, most likely not associated with the merger event.
