TITLE: GCN CIRCULAR NUMBER: 36508 SUBJECT: GRB 240516A ATCA radio observations DATE: 24/05/17 19:23:22 GMT FROM: Sarah Chastain at University of New Mexico <sarahichastain@gmail.com> S. Chastain (UNM), J. K. Leung (U. Toronto/HUJI), G. E. Anderson (Curtin University), A. Gulati (U. Sydney), L. Rhodes (U. Oxford), A. J. van der Horst (GWU) on behalf of the PanRadio GRB collaboration The Australia Telescope Compact Array (ATCA) performed observations of the long GRB 240516A detected by Swift-BAT (Parsotan et al., GCN 36493), Fermi-GBM (S. Bala et al., GCN 26499), and AstroSat CZTI (Joshi et al., GCN 36503) at 5.5, 9, 17 and 19 GHz as part of the Large ATCA "PanRadio GRB" follow-up programme C3542 (PI. Anderson). ATCA start observing on 2024-05-16 at 13:24 UT (~10 hours post-burst) and continued to observe until 21:00 UT on 2024-05-16. In our preliminary analysis, we find no radio source coincident with the Swift XRT uncataloged source (Parsotan et al., GCN 36493) with 3 sigma upper limits of 186, 126, 276 and 381 microJy/beam at 5.5, 9.0, 17 and 19 GHz, respectively. We thank the CSIRO Space and Astronomy staff for supporting these observations. We acknowledge the Gomeroi people as the traditional owners of the Observatory site. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (https://ror.org/05qajvd42) which is funded by the Australian Government for operation as a National Facility managed by CSIRO.
