AbstraktAbstract

Currently, the Baikal-GVD neutrino telescope data processing system analyzes the acquired data in real-time regime to search for a neutrino signal from astrophysical sources. This includes following up on multimessenger alerts such as high-energy (HE) neutrino alerts from IceCube, gamma-ray flares and gravitational wave events. The GVD online analysis system classifies events into HE and LE ranks for both upward-going muon tracks and cascades from all directions and correlates them with GCN notices within an average delay of 5 minutes. The comparison of real-time and offline processing modes, highlighting potential inaccuracies in event detection, is provided. Some recent results of correlation searches triggered by external alerts are shown, including gamma-ray activity of the blazar OP313 since December 2024 and the gravitational wave event S250206dm, as a likely candidate of NSBH merge in a binary system.
