Abstract:
We report the possible detection of the TDE 2025CYH with the radio telescope AMI-LA at 15.5 GHz.

We observed the field of the tidal disruption event (TDE) TDE2025CYH with the Arcminute Microkelvin Imager - Large Array (AMI-LA) for 4 hours on 2025-12-27, with a central frequency of 15.5 GHz. A point source is detected in the AMI-LA image at RA 18:34:47.29 DEC +31.50.12.15, consistent with the reported position of TDE2025CYH. The source is detected at a flux density of 0.556 +/- 0.094 mJy. The image RMS is 0.09 mJy.
We plan to perform follow-up observations with the AMI-LA and encourage further high-cadence multi-frequency radio observations with other facilities.
We thank the staff of MRAO for scheduling and performing this observation.
