Viscous Properties of Nickel-Containing Binary Metal Melts
R. M. Khusnutdinoff, R. R. Khairullina, A. L. Beltyukov +2
The paper presents the results of molecular dynamics study of the viscosity of nickel-containing binary metal melts for a wide range of temperatures, including the region of the eq…
Two types of distribution of the gas velocity dispersion of MaNGA galaxies
L. S. Pilyugin, I. A. Zinchenko, M. A. Lara-Lopez +2
The distribution of the gas velocity dispersion sigma across the images of 1146 MaNGA galaxies is analyzed. We find that there are two types of distribution of the gas velocity dis…
X-ray variability of the HMXB Cen X-3: evidence for inhomogeneous accretion flows
Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Konstantin Postnov +3
Cen X-3 is a compact high mass X-ray binary likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of two pointed XMM-Newton observat…
On the influence of multiple stellar populations in globular clusters on their medium-resolution integrated-light spectra
M. E. Sharina, V. V. Shimansky
We take a closer look at our published results of determination of ages, metallicities, helium mass fractions and abundances of chemical elements in Galactic globular clusters in o…
Flux-density measurements of the high-redshift blazar PSO J047.4478+27.2992 at 4.7 and 8.2 GHz with RATAN-600
T. Mufakharov, A. Mikhailov, Yu. Sotnikova +5
We report the first detection at 4.7 and 8.2 GHz with the RATAN-600 radio telescope of the source PSO J047.4478+27.2992, which has been announced as a blazar at z=6.1. The average…
Cosmological solutions in Einstein-Gauss-Bonnet gravity with static curved extra dimensions
Dmitry Chirkov, Alex Giacomini, Sergey A. Pavluchenko +1
In this paper we perform systematic investigation of all possible solutions with static compact extra dimensions and expanding three-dimensional subspace (``our Universe''). Unlike…
