Detection and luminosity-dependent evolution of the high-energy hump in the Be/X-ray pulsar 1A 1118-61
Alexander Salganik, Sergey S. Tsygankov, Sergey V. Molkov +12
Context. Accreting X-ray pulsars exhibit strong luminosity-dependent changes in their broad-band spectra. At high luminosities, their spectra are usually described by a power-law c…
X-ray and radio observations of the AMXP MAXI J1957+032 covering the 2022-2025 outbursts
Zhaosheng Li, Lucien Kuiper, Yuanyue Pan +12
We presented a comprehensive multi-epoch timing and multiwavelength analysis of the accreting millisecond X-ray pulsar MAXI J1957+032, covering two major outbursts in 2022 and 2025…
Discovery of a 0.8-mHz quasi-periodic oscillation in the transient X-ray pulsar SXP31.0 and associated timing transitions
Alexander Salganik, Sergey S. Tsygankov, Sergey V. Molkov +5
We present the first broadband spectral and timing study of the Be/X-ray pulsar XTE J0111.27317 (SXP31.0) during the first major outburst since its discovery in 1998. This giant…
Traces of wobbling accretion disk in X-ray pulsar Her X-1 from observations of the ART-XC telescope of the SRG observatory
V. M. Revnivtsev, K. A. Postnov, S. V. Molkov +5
Long uninterrupted observations of the X-ray binary system Her X-1 were performed with the Mikhail Pavlinsky ART-XC telescope of the Spectrum-Röntgen-Gamma (SRG) X-ray Observatory…
Hard X-rays and QPO in Swift J1727.8-1613: the rise and plateau of the 2023 outburst
I. Mereminskiy, A. Lutovinov, S. Molkov +5
We report on the detection of type-C quasi-periodic oscillations during the initial stages of the outburst of Swift J1727.8-1613 in 2023. Using data of the INTEGRAL observatory alo…
Complex variations of X-ray polarization in the X-ray pulsar LS V +44 17/RX J0440.9+4431
Victor Doroshenko, Juri Poutanen, Jeremy Heyl +109
We report on Imaging X-ray polarimetry explorer (IXPE) observations of the Be-transient X-ray pulsar LS V +44 17/RX J0440.9+4431 made at two luminosity levels during the giant outb…
