ZTF23aaoohpy/AT2023lcr: AMI-LA radio detection
Abstract
We report the detection of radio emission from the fast fading red transient ZTF23aaoohpy/AT2023lcr (Swain et al., GCN 34022) using the AMI-LA telescope. We observed the field of AT 2023lcr with the Arcminute Microkelvin Imager -Large Array (AMI-LA) for 4 hours on the 2023-06-21, with a central frequency of 15.5 GHz. The flux standard 3c286 was used to calibrate the bandpass response and flux scale of the AMI-LA and J1613+3412 was used as an interleaved complex gain calibrator. A point source is detected in the AMI-LA image at RA = 16:31:37.30 +/- 0.06 s, Dec = +26:22:01.0 +/- 3.0 arcsec, consistent with the reported position of AT 2023lcr. The source is detected at a flux density of 0.50 +/- 0.05 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.
