RXTE observations of X-ray transients IGRJ17091-3624 and IGRJ18539+072
A. A. Lutovinov, M. G. Revnivtsev
We present results of analysis of observations of two transient sources IGR J17091-3624 and IGR J18539+0727 in April 2003 with RXTE observatory. Obtained energy spectra of sources,…
First results of observations of transient pulsar SAXJ2103.5+4545 with the INTEGRAL observatory
A. Lutovinov, S. Molkov, M. Revnivtsev
We present preliminary results of observations of X-ray pulsar SAX J2103.5+4545 with INTEGRAL observatory in Dec 2002. Maps of this sky region in energy bands 3-10, 15-40, 40-100 a…
The spectrum of the cosmic X-ray background observed by RTXE/PCA
M. Revnivtsev, M. Gilfanov, R. Sunyaev +2
We have analyzed a large set of RXTE/PCA scanning and slewing observations performed between April 1996 and March 1999. We obtained the 3-20 keV spectrum of the cosmic X-ray backgr…
RXTE observations of strongly absorbed sources IGR J16318-4848 and IGR J16358-4726
M. Revnivtsev
Results of analysis of RXTE observations of strongly absorbed X-ray sources IGR J16318-4848 and IGR J16358-4726 are presented. Careful subtraction of Galactic ridge emission contri…
IGR J16318-4848: an X-ray source in a dense envelope?
M. Revnivtsev, S. Sazonov, M. Gilfanov +1
The hard X-ray source IGR J16318-4848 was recently discovered by the INTEGRAL observatory (Courvoisier et al.) and subsequently uncovered in archival data of ASCA observations in 1…
