Four years of wide-field search for nanosecond optical transients with the TAIGA-HiSCORE Cherenkov array
A. D. Panov, I. I. Astapov, G. M. Beskin +75
It has been previously demonstrated [Panov et al. Physics of Atomic Nuclei 84(2021)1037] that the TAIGA-HiSCORE Cherenkov array, originally built for cosmic ray physics and ultrahi…
On the Galactic origin of ultra-high energy cosmic rays
V. N. Zirakashvili, V. S. Ptuskin, S. I. Rogovaya
It is shown that the acceleration of particles by a powerful relativistic jet associated with the activity of a supermassive black hole in the Galactic center several million years…
Ultra high energy cosmic rays from past activity of Andromeda galaxy
V. N. Zirakashvili, V. S. Ptuskin, S. I. Rogovaya
It is shown that the relativistic jets associated with the growth and past activity of the supermassive black hole in the Andromeda galaxy could be the main source of cosmic rays w…
Role of the radiative stage for cosmic ray acceleration in SNRs
V. N. Zirakashvili, V. S. Ptuskin
We consider diffusive shock acceleration in supernova remnants throughout their evolution including a radiative stage. It is found that a more efficient acceleration and fast exit…
Cosmic ray acceleration in accretion flows of galaxy clusters
V. N. Zirakashvili, V. S. Ptuskin
We investigate acceleration of cosmic rays by shocks and accretion flows in galaxy clusters. Numerical results for spectra of accelerated particles and nonthermal emission are pres…
Cosmic ray acceleration in magnetic circumstellar bubbles
V. N. Zirakashvili, V. S. Ptuskin
We consider the diffusive shock acceleration in interstellar bubbles created by powerful stellar winds of supernova progenitors. Under the moderate stellar wind magnetization the b…
