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.
