Neutrino production in blazar radio cores
O. E. Kalashev, P. Kivokurtseva, S. Troitsky
Models of the origin of astrophysical neutrinos with energies from TeVs to PeVs are strongly constrained by multimessenger observations and population studies. Recent results point…
Diffuse neutrino flux measurements with the Baikal-GVD neutrino telescope
Baikal Collaboration, V. A. Allakhverdyan, A. D. Avrorin +55
We report on the first observation of the diffuse cosmic neutrino flux with the Baikal-GVD neutrino telescope. Using cascade-like events collected by Baikal-GVD in 2018--2021, a si…
Growing evidence for high-energy neutrinos originating in radio blazars
A. V. Plavin, Y. Y. Kovalev, Y. A. Kovalev +1
Evidence for bright radio blazars being high-energy neutrino sources was found in recent years. However, specifics of how and where these particles get produced still need to be de…
Parameters of axion-like particles required to explain high-energy photons from GRB 221009A
S. V. Troitsky
Recent astrophysical transient Swift J1913.1+1946 is possibly associated with the gamma-ray burst GRB 221009A at the redshift z=0.151. The transient was accompanied by very high-en…
High-energy neutrino-induced cascade from the direction of the flaring radio blazar TXS 0506+056 observed by Baikal-GVD in 2021
GVD Collaboration, A. K. Erkenov, N. A. Kosogorov +8
The existence of high-energy astrophysical neutrinos has been unambiguously demonstrated, but their sources remain elusive. IceCube reported an association of a 290-TeV neutrino wi…
Galactic contribution to the high-energy neutrino flux found in track-like IceCube events
Y. Y. Kovalev, A. V. Plavin, S. V. Troitsky
Astrophysical sources of neutrinos detected by large-scale neutrino telescopes remain uncertain. While there exist statistically significant observational indications that a part o…
Energy-dependent flavor ratios, cascade/track spectrum tension and high-energy neutrinos from magnetospheres of supermassive black holes
Kirill Riabtsev, Sergey Troitsky
The IceCube neutrino observatory measures the diffuse flux of high-energy astrophysical neutrinos by means of various techniques, and there exists a mild tension between spectra ob…
