Variability of X-ray pulsars in a hard energy band observed with INTEGRAL
A. Lutovinov, S. Tsygankov, M. Revnivtsev +5
We present the first results of the observations of the X-ray pulsars LMC X-4, 4U0352+309 and EXO1722-363 performed with the INTEGRAL observatory. The LMC X-4 was investigated duri…
Chandra localization of KS1731--260
M. Revnivtsev, R. Sunyaev
We present the analysis of the Chandra image of KS 1731-260. The improvement of the source localization (down to ~0.6'') allowed us to rule out 12 of 13 infrared companion candidat…
The study of the X-ray emission from the accreting black holes and neutron stars
M. Revnivtsev
The thesis studies the X-ray emission from the Galactic compact objects (accreting neutron stars and black holes), using mainly the RXTE data. In particular following results have…
Frequency resolved spectroscopy of Cyg X-1: fast variability of the Fe K_alpha line
M. Revnivtsev, M. Gilfanov, E. Churazov
We studied the frequency resolved energy spectra of Cyg X--1 during the standard low (hard) spectral state using the data of the Rossi X-Ray Timing Explorer. We found that the rela…
The X-ray Nova GRS 1739-278 near the Galactic Center
K. N. Borozdin, M. G. Revnivtsev, S. P. Trudolyubov +3
The soft X-ray nova GRS 1739-278 flared up in 1996 near the Galactic center. We present the observations of this interesting source, a black-hole candidate, with the instruments on…
Restrictions on the parameters of boundary layer and accretion disk of X-ray bursters in the low state
M. Revnivtsev, M. Gilfanov, E. Churazov +1
Using ASCA observations of several X-ray bursters in the low spectral state Lx~1-5x10^{36} erg/s) restrictions on the parameters of the accretion disk and the boundary layer were o…
