Probing the Galactic neutrino flux at neutrino energies above 200 TeV with the Baikal Gigaton Volume Detector
Recent observations of the Galactic component of the high-energy neutrino flux, together with the detection of the diffuse Galactic gamma-ray emission up to sub-PeV energies, open new possibilities to study the acceleration and propagation of cosmic rays in the Milky Way. At the same time, both larg...

| description | Recent observations of the Galactic component of the high-energy neutrino
flux, together with the detection of the diffuse Galactic gamma-ray emission up
to sub-PeV energies, open new possibilities to study the acceleration and
propagation of cosmic rays in the Milky Way. At the same time, both large
non-astrophysical backgrounds at TeV energies and scarcity of neutrino events
in the sub-PeV band currently limit these analyses. Here we use the sample of
cascade events with estimated neutrino energies above 200 TeV, detected by the
partially deployed Baikal Gigaton Volume Detector (GVD) in six years of
operation, to test the continuation of the Galactic neutrino spectrum to
sub-PeV energies. We find that the distribution of the arrival directions of
Baikal-GVD cascades above 200 TeV in the sky suggests an excess of neutrinos
from low Galactic latitudes. We find the excess above 200 TeV also in the most
recent IceCube public data sets, both of cascades and tracks. The significant
(3.6 sigma in the combined analysis) flux of Galactic neutrinos above 200 TeV
challenges often-used templates for neutrino search based on cosmic-ray
simulations. |

flux, together with the detection of the diffuse Galactic gamma-ray emission up
to sub-PeV energies, open new possibilities to study the acceleration and
propagation of cosmic rays in the Milky Way. At the same time, both large
non-astrophysical backgrounds at TeV energies and scarcity of neutrino events
in the sub-PeV band currently limit these analyses. Here we use the sample of
cascade events with estimated neutrino energies above 200 TeV, detected by the
partially deployed Baikal Gigaton Volume Detector (GVD) in six years of
operation, to test the continuation of the Galactic neutrino spectrum to
sub-PeV energies. We find that the distribution of the arrival directions of
Baikal-GVD cascades above 200 TeV in the sky suggests an excess of neutrinos
from low Galactic latitudes. We find the excess above 200 TeV also in the most
recent IceCube public data sets, both of cascades and tracks. The significant
(3.6 sigma in the combined analysis) flux of Galactic neutrinos above 200 TeV
challenges often-used templates for neutrino search based on cosmic-ray
simulations.</abstract><doi>10.48550/arxiv.2411.05608</doi><oa>free_for_read</oa></addata></record> |
