TITLE: GCN CIRCULAR NUMBER: 39507 SUBJECT: LIGO/Virgo/KAGRA S250227y: Retraction of GW compact binary merger candidate DATE: 25/02/27 01:38:00 GMT FROM: chl20171@outlook.com

The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report:

The trigger S250227y is no longer considered to be a candidate of interest. This candidate was initially identified by one or more early-warning analyses by matching partial signal templates to the data. Analysis of additional data up to the putative merger time, with full signal templates, did not make a significant detection, indicating that the initial candidate was likely due to transient noise.
