GRB 241105A: ATCA radio detection

We re-observed GRB 241105A (Fermi GBM Collaboration, GCN 38085) with the Australia Telescope Compact Array (ATCA) 15 days post-burst on 2024-11-20 (11:00-19:00 UT). We detected a radio source coincident with the location of the optical counterpart (Julakanti et al. GCN 38088, Izzo et al., GCN 38097; SVOM/VT team, GCN 38099; Hu et al., GCN 38106; Siegel et al., GCN 38110; Dichiara et al., GCN 38111; Rastinejad et al., GCN 38113; Tsalapatas et al., GCN 38119) at 9 GHz with a flux density of ~100 microJy/beam (rms of 11 microJy/beam). Further observations are planned. 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.
