Preheating of the early Universe by radiation from high-mass X-ray binaries
Sergey Sazonov, Ildar Khabibullin
Using a reliably measured intrinsic (i.e. corrected for absorption effects) present-day luminosity function of high-mass X-ray binaries (HMXBs) in the 0.25-2 keV energy band per un…
Bright end of the luminosity function of high-mass X-ray binaries: contributions of hard, soft and supersoft sources
Sergey Sazonov, Ildar Khabibullin
Using a spectral analysis of bright Chandra X-ray sources located in 27 nearby galaxies and maps of star-formation rate (SFR) and ISM surface densities for these galaxies, we const…
Polarization and long-term variability of Sgr A* X-ray echo
E. Churazov, I. Khabibullin, G. Ponti +1
We use a model of the molecular gas distribution within ~100 pc from the center of the Milky Way (Kruijssen, Dale & Longmore) to simulate time evolution and polarization properties…
Not that long time ago in the nearest galaxy: 3D slice of molecular gas revealed by a 110 years old flare of Sgr A*
E. Churazov, I. Khabibullin, R. Sunyaev +1
A powerful outburst of X-ray radiation from the supermassive black hole Sgr A* at the center of the Milky Way is believed to be responsible for the illumination of molecular clouds…
Polarization of thermal bremsstrahlung emission due to electron pressure anisotropy
S. Komarov, I. Khabibullin, E. Churazov +1
Astrophysical plasmas are typically magnetized, with the Larmor radii of the charged particles many orders of magnitude smaller than their collisional mean free paths. The fundamen…
Is SS 433 a misaligned ultraluminous X-ray source? Constraints from its reflected signal in the Galactic plane
Ildar Khabibullin, Sergey Sazonov
We evaluate the emission that must arise due to reflection of the putative collimated X-ray radiation of SS 433 by atomic gas and molecular clouds in the Galactic plane and compare…
