Carpet-3 detection of a photon-like air shower with estimated primary energy above 100 TeV in a spatial and temporal coincidence with GRB 221009A
D. D. Dzhappuev, I. M. Dzaparova, T. A. Dzhatdoev +18
The brightest cosmic gamma-ray burst (GRB) ever detected, GRB 221009A, was accompanied by photons of very high energies. These gamma rays may be used to test both the astrophysical…
Upper limits on the isotropic diffuse flux of cosmic PeV photons from Carpet-2 observations
D. D. Dzhappuev, Yu. Z. Afashokov, I. M. Dzaparova +19
Isotropic diffuse gamma-ray flux in the PeV energy band is an important tool for multimessenger tests of models of the origin of high-energy astrophysical neutrinos and for new-phy…
Observation of photons above 300 TeV associated with a high-energy neutrino from the Cygnus region
D. D. Dzhappuev, Yu. Z. Afashokov, I. M. Dzaparova +19
Galactic sites of acceleration of cosmic rays to energies of order 10^15 eV and higher, dubbed PeVatrons, reveal themselves by recently discovered gamma radiation of energies above…
Carpet-2 search for gamma rays above 100 TeV in coincidence with HAWC and IceCube alerts
D. D. Dzhappuev, Yu. Z. Afashokov, I. M. Dzaparova +16
We report on the search of astrophysical gamma rays with energies in the 100 TeV to several PeV range arriving in directional and temporal coincidence with public alerts from HAWC…
Optical Observations Reveal Strong Evidence for High Energy Neutrino Progenitor
V. M. Lipunov, V. G. Kornilov, K. K. Zhirkov +32
We present the earliest astronomical observation of a high energy neutrino error box in which its variability was discovered after high-energy neutrinos detection. The one robotic…
Multimessenger search for evaporating primordial black holes
V. B. Petkov, E. V. Bugaev, P. A. Klimai
Primordial black holes (PBHs) are black holes which may form in the early Universe through the gravitational collapse of primordial cosmological density fluctuations. Due to Hawkin…
