  • A reflection model for the cyclotron lines in the spectra of X-ray pulsars 
    Poutanen J.; Mushtukov A.; Suleimanov V.; Tsygankov S.; Nagirner D.; Doroshenko V.; Lutovinov A. (2013)
    Cyclotron resonance scattering features observed in the spectra of some X-ray pulsars show significant changes of the line energy with the pulsar luminosity. At high luminosities, these variations are often associated with ...
  • Dramatic spectral transition of X-ray pulsar GX 304-1 in low luminous state 
    Tsygankov S.; Rouco Escorial A.; Suleimanov V.; Mushtukov A.; Doroshenko V.; Lutovinov A.; Wijnands R.; Poutanen J. (2019)
    © 2018 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society. We report on the discovery of a dramatic change in the energy spectrum of the X-ray pulsar GX 304-1 appearing at low ...
  • Middle aged γ-ray pulsar J1957+5033 in X-rays: Pulsations, thermal emission, and nebula 
    Zyuzin D.A.; Karpova A.V.; Shibanov Y.A.; Potekhin A.Y.; Suleimanov V.F. (2021)
    We analyse new XMM-Newton and archival Chandra observations of the middle-aged γ-ray radio-quiet pulsar J1957+5033. We detect, for the first time, X-ray pulsations with the pulsar spin period of the point-like source ...
  • Thermal Emission and Magnetic Beaming in the Radio and X-Ray Mode-switching PSR B0943+10 
    Rigoselli M.; Mereghetti S.; Turolla R.; Taverna R.; Suleimanov V.; Potekhin A. (2019)
    © 2019. The American Astronomical Society. All rights reserved. PSR B0943+10 is a mode-switching radio pulsar characterized by two emission modes with different radio and X-ray properties. Previous studies, based on simple ...
