Abstract

The status of the Baikal-GVD neutrino telescope after the winter 2023 deployment campaign that results in 3456 optical modules installed on 96 vertical strings is reviewed. The Baikal-GVD data collected in 2018-2022 show the presence of cosmic neutrino flux in high-energy cascade events consistent with observations by the IceCube neutrino telescope. An identification of the first high-energy muon neutrino candidate is presented as a result of analysis of track-like events.
