High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S
F. Aharonian, F. Ait Benkhali, J. Aschersleben +144
Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…
S2-star dynamics probing the Galaxy core cluster
N. Galikyan, Sh. Khlghatyan, A. A. Kocharyan +1
The star cluster surrounding the supermassive black hole in the center of Milky Way is probed using the data on the S2 star. The value of precession found at the physics-informed n…
Improving the Electro-Optical Properties of MoS/rGO Hybrid Nanocomposites Using Liquid Crystals
A. Vasilev, Y. Melikyan, M. Zhezhu +5
Hybrid systems of two-dimensional (2D) materials (such as graphene-family materials and 2D transition metal dichalcogenides) are attracting much attention due to their distinctive…
The contribution of winds of star clusters to the Galactic cosmic-ray population
Giada Peron, Sabrina Casanova, Stefano Gabici +2
Cosmic rays are energetic nuclei that permeate the entire Galactic disk. Their existence requires the presence of powerful particle accelerators. While Galactic supernova explosion…
Bulk viscosity of two-color superconducting quark matter in neutron star mergers
Mark Alford, Arus Harutyunyan, Armen Sedrakian +1
We study the bulk viscosity of moderately hot and dense, neutrino-transparent color superconducting quark matter arising from weak-interaction-driven direct URCA processes. The qua…
Smearing of primordial gravitational waves
M. Samsonyan, A. A. Kocharyan, V. G. Gurzadyan
A mechanism for smearing of the primordial gravitational waves during the radiation-dominated phase of the evolution of the Universe is considered. It is shown that the primordial…
