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…
A wide-field X-ray search for the Geminga pulsar halo with SRG/ART-XC
Roman Krivonos, Silvia Manconi, Vadim Arefiev +8
Searches for the putative large-scale X-ray halo around the Geminga pulsar have been extensively performed using various narrow field-of-view X-ray telescopes. In this paper, we pr…
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…
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…
A Probabilistic Method of Background Removal for High Energy Astrophysics Data
Steven Ehlert, Chien-Ting Chen, Doug A. Swartz +6
We present a new statistical method for constructing background subtracted measurements from event list data gathered by X-ray and gamma ray observatories. This method was initiall…
