TITLE: GCN CIRCULAR NUMBER: 38659 SUBJECT: EP241113a: Non-detection in Radio Follow-up Observations with eMERLIN DATE: 24/12/24 03:00:49 GMT FROM: Tao An at SHAO, CAS <antao@shao.ac.cn> Ailing Wang (IHEP, China), Tao An (SHAO, China), Cuiyuan Dai, Xiang-Yu Wang (Nanjing University, China), on behalf of the EP radio follow-up team: We report radio follow-up observations of EP241113a, which was initially discovered by the EP team (Liu et al., GCN 38211). A candidate optical counterpart was subsequently identified by Rossi et al. (GCN 38233), with a tentative redshift of z ~ 1.5 (Quirola-Vasquez et al., GCN 38449). We conducted follow-up observations using the enhanced Multi Element Remotely Linked Interferometer Network (eMERLIN). Our observations targeted the EP/FXT position at R.A. = 131.9964°, DEC = 52.3815° (J2000). The observations were carried out in two epochs: 1. 2024-11-18 20:00 UTC to 2024-11-19 12:21 UTC 2. 2024-11-23 08:30 UTC to 2024-11-27 14:49 UTC No significant radio emission was detected at 5 GHz in either epoch. We derive 3σ upper limits of: - First epoch: 1.0 mJy - Second epoch: 0.2 mJy We acknowledge the eMERLIN TAC for approving this DDT proposal and the operations team for their rapid scheduling and excellent support.
