On the nature of the X-ray pulsar XTE J1859+083 and its broadband properties
Alexander Salganik, Sergey S. Tsygankov, Anlaug A. Djupvik +5
This work is devoted to the study of the broadband 0.8-79 keV spectral and timing properties of the poorly studied X-ray pulsar XTE J1859+083 during its 2015 outburst based on the…
Broad-band analysis of X-ray pulsar 2S 1845024
Armin Nabizadeh, Sergey S. Tsygankov, Sergey V. Molkov +4
We present results of detailed investigation of the poorly studied X-ray pulsar 2S 1845024 based on the data obtained with observatory during the type I outburst in 201…
Study of the X-ray Pulsar XTE J1946+274 with NuSTAR
A. S. Gorban, S. V. Molkov, S. S. Tsygankov +1
We present the results of our spectral and timing analysis of the emission from the transient X-ray pulsar XTE J1946+274 based on the simultaneous NuSTAR and Swift/XRT observations…
Black hole spin-orbit misalignment in the X-ray binary MAXI J1820+070
Juri Poutanen, Alexandra Veledina, Andrei V. Berdyugin +10
The observational signatures of black holes in x-ray binary systems depend on their masses, spins, accretion rate and the misalignment angle between the black hole spin and the orb…
SRG/ART-XC, Swift, NICER and NuSTAR study of different states of the transient X-ray pulsar MAXI J0903-531
Sergey S. Tsygankov, Sergey V. Molkov, Victor Doroshenko +6
The results of the broadband spectral and timing study of the recently discovered transient X-ray pulsar MAXI J0903-531 in a wide range of luminosities differing by a factor of ~30…
Losing a minute every two years: SRG X-ray view on the rapidly accelerating X-ray pulsar SXP1323
I. A. Mereminskiy, A. A. Mushtukov, A. A. Lutovinov +4
SXP 1323 is a peculiar high-mass X-ray binary located in the Small Magellanic Cloud, renowned for its rapid spin-up. We investigate for the first time broadband X-ray properties of…
