TITLE: GCN CIRCULAR NUMBER: 36351 SUBJECT: Additional DECam GW-MMADS Candidates from three nights of observations DATE: 24/04/30 03:04:39 GMT FROM: Igor Andreoni at JSI/UMD/NASA <igor.andreoni@gmail.com> Lei Hu (CMU), Tomás Cabrera (CMU), Antonella Palmese (CMU), Igor Andreoni (UMD), Brendan O'Connor (CMU), Keerthi Kunnumkai (CMU) report on behalf of the GW-MMADS team: We report additional candidates from the DECam GW-MMADS survey program (GCN 36245, GCN 36273, GCN 36298, GCN 36317) follow-up of the LIGO/Virgo/KAGRA event S240422ed (GCN 36236, GCN 36240). We ran the SFFT difference imaging (Hu et al. 2022) on the available images from the first three nights of observations (between 2023-04-22 23:37 and 2024-04-25 02:50 UTC), filtered out likely stars and moving objects, and visually inspected the remaining transients. We reported on TNS new transients within the LVK 95% CI area, and report here the additional candidate counterparts with at least two detections and possibly associated with a galaxy. +-------------------------+------------+------------+-----------+-----------+ | id | tns | ra | dec | comment | |-------------------------+------------+------------+-----------+-----------| | T202404240826256m240205 | AT 2024hiw | 126.60656 | -24.03458 | [1] | | T202404240824462m330712 | AT 2024hiu | 126.19269 | -33.12002 | [2] | +-------------------------+------------+------------+-----------+-----------+ [1] ~2.3 arcsec from a galaxy [2] ~3.8 arcsec from a galaxy (possibly from a star on top of a galaxy based on Gaia DR3 and visual inspection) We thank the CTIO and NOIRLab staff for supporting these observations and the data calibrations.
