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...

Each cluster can operate as stand-alone detector. layout optimized for the...
TAIGA stands for ``Tunka Advanced Instrument cosmic ray physics and Gamma Astronomy'' is a project to built complex, hybrid detector system ground-based gamma-ray astronomy from few TeV several PeV, studies 100 1 EeV. will search ``PeVatrons'' (ultra-high energy sources) measure the composition spectrum of rays in knee region (100 TeV–10 PeV) with good resolution high statistics. include Tunka-HiSCORE — an array wide-angle air Cherenkov stations, Imaging Atmospheric Telescopes, particle...
Data obtained with two detectors located at the Tunka Cosmic Ray facility are presented. The Cherenkov light array for registration of extensive air showers (EAS) Tunka-133 collected data during 5 winter seasons since 2009 to 2014. differential energy spectrum all particles and dependence average maximum depth on in range 6 · 1015−1018 eV measured 1540 hours observation
The TAIGA observatory addresses ground-based gamma-ray astronomy at energies from a few TeV to several PeV, cosmic ray physics 100 EeV as well for search axion-like particles, Lorentz violations and another evidence of New Physics. In 2020 year one square kilometer setup should be put in operation.
A review of the Baikal-GVD neutrino telescope status after winter 2024 deployment campaign that results in 4 104 opticalmodules installed on 114 vertical strings is presented. The analysis data collected 2018-2023 show presence cosmic flux high-energy cascade channel consistent with observations by IceCube telescope. Track-like events identification first muon candidates.

The physical motivations and advantages of the new gamma-observatory TAIGA (Tunka Advanced Instrument for cosmic ray physics Gamma Astronomy) is presented. array a complex, hybrid detector ground-based gamma-ray astronomy energies from few TeV to several PeV as well studies 100 EeV. will include wide angle Cherenkov TAIGA-HiSCORE with ~5 km2 area, net 16 I ACT telescopes (with FOV about 10x10 degree), muon detectors total area up 2000-3000 m2 radio Tunka-Rex.
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.
