TITLE: GCN CIRCULAR NUMBER: 39615 SUBJECT: EP250304a: MeerKAT detection of a possible radio counterpart DATE: 25/03/07 16:30:01 GMT FROM: Francesco Carotenuto at INAF/OAR francesco.carotenuto@inaf.it
F. Carotenuto (INAF/OAR), J. Bright (University of Oxford), P. G. Jonker (Radboud University) report on behalf of a larger collaboration:
We observed the Fast X-ray Transient EP250304a (Chen et al., GCN 39580) with the MeerKAT radio telescope at 3.0 GHz for a total of 1 hour starting on March 7th 2024 at 04:36 UTC. J1939-6342 and PKS 1320-446 were used as flux and complex gain calibrators, respectively. Using the South African Radio Astronomy Observatory Science Data Pipeline image, we find an unresolved source at the position of the optical counterpart of the FXT (Liu et al., GCN 39583, Saccardi et al., GCN 39585) with a flux density of ~100 uJy/beam. The rms noise in the field is 6.5 uJy/beam. Further MeerKAT observations are planned.
We thank the staff at the South African Radio Astronomy Observatory for the rapid scheduling of these observations.
