Description

Baikal-GVD is a cubic kilometer-scale neutrino detector currently under construction in Lake Baikal, Russia. The detector has been taking science data in partial configurations since 2016 and is now 70% complete. We present a search for astrophysical point-like neutrino sources using track-like events collected by Baikal-GVD during the seasons 2019-2023. No significant neutrino source has been found in this analysis. Therefore we compute upper limits for a selection of candidate objects. The results are compared to published results from IceCube, ANTARES and KM3NeT.
