AbstraktAbstract

The Baikal-GVD neutrino telescope, located in Lake Baikal, Russia, is designed to detect high-energy neutrinos and perform real-time searches for astrophysical sources associated with multimessenger signals, such as gamma-ray bursts, gravitational waves, and neutrino alerts. Since 2021, the implementation of an automated system has reduced analysis delays to 3-10 minutes, enabling efficient classification of events into upward-going tracks (muon neutrinos) and high-energy cascades (all-flavor neutrinos). The telescope’s external alert followup system employs InfluxDB for time-series data management and Grafana for online data visualization and correlation analysis. Using ON/OFF algorithms and techniques for identifying spatial-temporal coincidences, the real-time system detects potential signals and evaluates their significance using the maximum likelihood method. In cases where no significant signal is detected, upper limits on neutrino fluxes are calculated.
