Fast Radio Bursts as Probes of Magnetic Fields in Galaxies at z < 0.5
We present a sample of nine fast radio bursts (FRBs) from which we derive magnetic field strengths of the host galaxies represented by normal, z < 0.5 star-forming galaxies with stellar masses M _* ≈ 10 ^8 –10 ^10.5 M _⊙ .

On irregularities in the cosmic ray spectrum of \(10^{16}-10^{18}\) eV range
Existing small, medium and large arrays for the study of cosmic rays of ultra-high energies are aimed for obtaining information about our galaxy and extragalactic space, namely to search and study astronomical objects that produce the flux of ...

CRPropa high statistics simulations for UHECR anisotropy studies [PDF]
Despite the great progress made by modern cosmic ray observatories, the origin and acceleration mechanism of ultra-high-energy cosmic rays (UHECRs) remains unsolved problems to this day.

Model of Super-Alfvénic MHD Turbulence and Statistics of Polarization
MHD turbulence driven at velocities higher than the Alfvén velocity, i.e., super-Alfvénic turbulence, is widely spread in astrophysical environments, including galaxy clusters and molecular clouds.

CTAO sensitivity to axion-like particles [PDF]
Axion-like particles (ALPs) are a common feature in several extensions of the StandardModel, arising, for example, as a solution to the strong CP problem in quantum chromodynamics, or as a prediction of string theories.
