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…
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…
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…
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…
Cygnus X-3 revealed as a Galactic ultraluminous X-ray source by IXPE
Alexandra Veledina, Fabio Muleri, Juri Poutanen +127
The accretion of matter by compact objects can be inhibited by radiation pressure if the luminosity exceeds the critical value, known as the Eddington limit. Discovery of ultralumi…
SRG/ART-XC discovery of SRGAJ144459.2-604207: a well-tempered bursting accreting millisecond X-ray pulsar
S. V. Molkov, A. A. Lutovinov, S. S. Tsygankov +7
We report on the discovery of the new accreting millisecond X-ray pulsar SRGAJ144459.2-604207 using the SRG/ART-XC data. The source was observed twice in February 2024 during the d…
