INTEGRAL insight into the inner parts of the Galaxy. High mass X-ray binaries
A. Lutovinov, M. Revnivtsev, M. Gilfanov +3
Since its launch INTEGRAL has devoted a significant fraction of its observing time to the Galactic plane region. We present the results of INTEGRAL observations of the inner spiral…
Broadband Observations of the Transient X-ray Pulsar SAX J2103.5+4545
E. V. Filippova, A. A. Lutovinov, P. E. Shtykovsky +5
We investigated the optical, X-ray, and gamma-ray variability of the pulsar SAX J2103.5+4545. Our timing and spectral analyses of the X-ray and gamma-ray emissions from the source…
INTEGRAL detection of a long powerful burst from SLX1735-269
S. Molkov, M. Revnivtsev, A. Lutovinov +1
We present results of analysis of a bursting behavior of a low mass X-ray binary system SLX 1735-269 during INTEGRAL observations of the Galactic Center region in 2003. There were…
Hard X-ray view of the past activity of Sgr A* in a natural Compton mirror
M. G. Revnivtsev, E. M. Churazov, S. Yu. Sazonov +6
We report the association of the recently discovered hard X-ray source IGR J17475-2822 with the giant molecular cloud Sgr B2 in the Galactic Center region. The broad band (3-200 ke…
An apparently normal gamma-ray burst with an unusually low luminosity
S. Sazonov, A. Lutovinov, R. Sunyaev
Much of progress in gamma-ray bursts has come from the studies of distant events (redshift z~1). The brightest GRBs are the most collimated events and seen across the Universe due…
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…
