Gravitational wave astronomy: astrophysical and cosmological inferences
Konstantin Postnov, Nikita Mitichkin
We briefly discuss the most prominent results and specific sources detected by gravitational-wave observatories LIGO-Virgo during first three O1-O3 runs, as well as possible astrop…
On the appearance of non-local MRI in Keplerian accretion discs
Nikolay Shakura, Konstantin Postnov, Dmitry Kolesnikov +1
We revisit the modal analysis of small perturbations in Keplerian ideal gas flows leading to magneto-rotational instability (MRI) using the non-local approach. We consider the case…
Search for pre-burst emission from binary neutron star mergers with Spectrum-Roentgen-Gamma
I. A. Mereminskiy, A. A. Lutovinov, K. A. Postnov +12
Close binary systems consisting of two neutron stars (BNS) emit gravitational waves, that allow them to merge on timescales shorter than Hubble time. It is widely believed, that NS…
Phase-resolved spectroscopic analysis of the eclipsing black hole X-ray binary M33 X-7: System properties, accretion, and evolution
V. Ramachandran, L. M. Oskinova, W. -R. Hamann +10
M33 X-7 is the only known eclipsing black hole high mass X-ray binary. The system is reported to contain a very massive O supergiant donor and a massive black hole in a short orbit…
Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
Evidence for neutron star triaxial free precession in Her X-1 from Fermi/GBM pulse period measurements
Dmitry Kolesnikov, Nikolai Shakura, Konstantin Postnov
Her X-1/HZ Her is one of the best studied accreting X-ray pulsars. In addition to the pulsating and orbital periods, the X-ray and optical light curves of the source exhibit an alm…
