The Tunka-Grande scintillation array is a part of a single TAIGA experimental complex located in the Tunka Valley, 50 km from the Lake Baikal. It consists of 19 observation stations deployed on an area of about 0.5 km². The main aim of the Tunka-Grande facility is a detailed study of the energy spectrum and mass composition of cosmic rays in the energy range from 10 PeV to 1 EeV by detecting the charged and muon component of EAS. The article presents a method for reconstructing the parameters of the EAS and primary cosmic rays, the cosmic rays energy spectrum based on 4 measurement seasons, and compares the results obtained with the data of the Tunka-133 and TAIGA-HiSCORE Cherenkov arrays.

Физико-математические науки, 16, № S1.2, с. 410-416 (2023)

A new experimental detector cluster for the TAIGA-IACT telescope has been developed. The cluster contains 28 pixels based on MicroFJ-60035 silicon photomultipliers, whose signal is digitized with an analog memory chip (switched capacitor array) DRS4 at a frequency of up to 5 GHz. The paper describes the device and the operation principles of the detector cluster, reveals the peculiarities encountered in the development process. Dark chamber tests of the cluster with a point source of short pulses of ultraviolet light have allowed us to obtain dependencies of the cluster conversion coefficient and the maximum value of the recorded signal on the overvoltage of the silicon detectors.

Физико-математические науки, 16, № S1.2, с. 474-479 (2023)

We report preliminary results of the search in the Konus-Wind experiment data for hard X-ray/soft γ-ray emission in coincidence with publicly reported fast radio bursts (FRBs). We find no significant associations for any of the 581 FRBs in our sample and report upper limits to the high-energy fluence/peak flux for three spectral shapes, which generally describe short GRB, long GRB and magnetar giant flare spectra. In addition to study each individual FRB, we perform a stacking analysis of the bursts from each repeating source in our sample and a separate stacking analysis of the bursts from the non-repeating FRBs. We find no statistically significant excess of the cumulative emission over background level for either case.

Mildly-relativistic outflows with shocks of velocities 0.1–0.7c were deduced from multiwavelength observations of powerful fast transient sources. These outflows are associated with merging relativistic objects, relativistic supernovae and fast blue optical transients. Relativistic magneto-hydrodynamic (RMHD) models of these objects rely on the equation of state of the fluid, which is a collisionless plasma with a contribution of non-thermal components. In this paper, we present kinetic simulations of mildly-relativistic shocks with Particle-in-Cell and Monte-Carlo techniques to derive the adiabatic index of plasma in the shock downstream directly from the particle distributions, which can be implemented into the RMHD models.
