Abstract Recent observations of the Galactic component high-energy neutrino flux, together with detection diffuse gamma-ray emission up to sub-PeV energies, open new possibilities study acceleration and propagation cosmic rays in Milky Way. At same time, both large nonastrophysical backgrounds at TeV energies scarcity events band currently limit these analyses. Here, we use sample cascade estimated above 200 TeV, detected by partially deployed Baikal Gigaton Volume Detector (GVD) 6 yr...

The Baikal-GVD neutrino telescope collaboration reports observing the diffuse cosmic flux. Relying on cascade events produced predominantly by electron and tau neutrinos, they observe a significant excess of over what is expected from atmospheric background. power law fit flux observation itself are consistent with independent confirmation landmark results IceCube.

Baikal-GVD has recently published its first measurement of the diffuse astrophysical neutrino flux, performed using high-energy cascade-like events. We further explore cascade dataset collected in 2018-2022, with aim to identify possible associations between neutrinos and known sources. leverage relatively high angular resolution telescope (2-3 deg.), made by use liquid water as detection medium, enabling study point sources even estimate telescope's sensitivity channel for refine our...

The progress in the construction and operation of Baikal Gigaton Volume Detector Lake is reported. detector designed for search high energy neutrinos whose sources are not yet reliably identified. It currently includes over 2000 optical modules arranged on 64 strings, providing an effective volume 0.4 km3 cascades with above 100 TeV. We review scientific case Baikal-GVD, plan, first results from partially built experiment, which largest neutrino telescope Northern Hemisphere still growing up.
