Low-mass X-ray binaries in the bulge of the Milky Way
M. Revnivtsev, A. Lutovinov, E. Churazov +4
We study the population of low-mass X-ray binaries (LMXBs) in the Galactic bulge using the deep survey of this region by the IBIS telescope aboard the INTEGRAL observatory. Thanks…
Boundary layer emission in luminous LMXBs
M. Gilfanov, M. Revnivtsev
We show that aperiodic and quasiperiodic variability of bright LMXBs - atoll and Z- sources, on ~sec - msec time scales is caused primarily by variations of the boundary layer lumi…
Origin of the Galactic ridge X-ray emission
M. Revnivtsev, S. Sazonov, M. Gilfanov +2
We analyze a map of the Galactic ridge X-ray emission (GRXE) constructed in the 3-20 keV energy band from RXTE/PCA scan and slew observations. We show that the GRXE intensity close…
X-ray variability, viscous time scale and Lindblad resonances in LMXBs
M. Gilfanov, V. Arefiev
Based on RXTE/ASM and EXOSAT/ME data we studied X-ray variability of persistent LMXBs in the 1e-8 - 1e-1 Hz frequency range, aiming to detect features in their power density spectr…
Constraints on the luminosity of the stellar remnant in SNR1987A
P. Shtykovskiy, A. Lutovinov, M. Gilfanov +1
We obtain photometric constraints on the luminosity of the stellar remnant in SNR1987A using XMM-Newton and INTEGRAL data. The upper limit in the 2--10 keV band based on the XMM-Ne…
X-ray binaries and ultra-luminous X-ray sources in nearby and distant galaxies
M. Gilfanov
We review recent results on populations of compact X-ray sources in normal galaxies. The luminosity distributions of low and high mass X-ray binaries in nearby galaxies appear to b…
