TITLE: GCN CIRCULAR NUMBER: 21537 SUBJECT: LIGO/Virgo G298048: ATCA observations of candidate host galaxies DATE: 17/08/18 04:04:00 GMT FROM: Tara Murphy at U of Sydney K. Bannister (CSIRO), C. Lynch (University of Sydney), D. Kaplan (UWM), T. Murphy (University of Sydney), D. Dobie (University of Sydney) on behalf of the VAST collaboration. We are currently observing candidate host galaxies in the LIGO/Virgo G298048 localisation volume with the Australia Telescope Compact Array (LVC GCN #21513, sky map; LVC GCN #21519, 54 nearby galaxies). We are observing at two central frequencies of 8.5 GHz and 10.5 GHz, each with a bandwidth of 2 GHz. Observations started at 2017-08-18 01:00 UTC. Analysis of this data is underway. Subsequent epochs are planned. Thank you to CSIRO staff for supporting these observations. -- A/PROF TARA MURPHY | ARC Future Fellow Sydney Institute for Astronomy | School of Physics | Faculty of Science THE UNIVERSITY OF SYDNEY Room 358, Physics Building A28 The University of Sydney | NSW | 2006 T +61 2 9351 3041 E tara@physics.usyd.edu.au http://www.physics.usyd.edu.au/~tara https://www.coursera.org/learn/data-driven-astronomy
