TITLE: GCN CIRCULAR NUMBER: 44088 SUBJECT: EP260214b: ATCA 6 GHz detection DATE: 26/03/23 15:25:11 GMT FROM: Aishwarya L Thakur at INAF-IAPS, Rome <aishth@outlook.com> G. Gianfagna, G. Bruni, A. L. Thakur, M. Fanelli, L. Piro (INAF-IAPS) report: We re-observed the Fast X-ray Transient EP260214b (J Yang et al., GCN 43744, H Yang et al., GCN 43779) with the Australian Telescope Compact Array (ATCA) radio telescope using the 4-cm receiver. Observations were performed on March 20 2026 (at a mean epoch of ~34 days after the EP trigger and 17 days after our last observation; see Gianfagna et al., GCN 43924) for a total of 5 hours. Data were reduced and imaged with standard CASA procedures. The final 6 GHz image has an RMS of 12 uJy/beam. We detect radio emission at a flux density of ~0.04 mJy at a position consistent with the optical counterpart (He et al.). GCN 43745, Watson et al. GCN 43747, Le Floch et al. GCN 43749, Pérez-Fournon et al. GCN 43750, Russeil et al. 43752,Li et al. GCN 43755, Vijayjumar et al. GCN 43757, Becerra et al. GCN 43758, Yang et al. GCN 43760, Aaryan et al. GCN 43762, Bochenek et al. GCN 43764, Kar et al. GCN 43774, Volnova et al. GCN 43775). Further ATCA observations are planned. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (grid.421683.a), which is funded by the Australian Government for operation as a National Facility managed by CSIRO. We acknowledge the Gomeroi people as the traditional owners of the Observatory site.
