INTEGRAL detection of hard X-rays from NGC 6334: Nonthermal emission from colliding winds or an AGN?
A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +12
We report the detection of hard X-ray emission from the field of the star-forming region NGC 6334 with the the International Gamma-Ray Astrophysics Laboratory INTEGRAL. The JEM-X m…
INTEGRAL and XMM-Newton observations of the X-ray pulsar IGR J16320-4751/AX J1631.9-4752
J. Rodriguez, A. Bodaghee, P. Kaaret +16
We report on observations of the X-ray pulsar IGR J16320-4751 (a.k.a. AX J1631.9-4752) performed simultaneously with INTEGRAL and XMM-Newton. We refine the source position and iden…
Using the ROSAT Catalogues to find counterparts for the second IBIS/ISGRI Survey Sources
J. B. Stephen, L. Bassani, A. Malizia +6
The second IBIS/ISGRI survey has produced a catalogue containing 209 hard X-ray sources visible down to a flux limit of around 1 milliCrab. The point source location accuracy of ty…
Hard X-ray Emission Clumps in the gamma-Cygni Supernova Remnant: an INTEGRAL-ISGRI View
A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +12
Spatially resolved images of the galactic supernova remnant G78.2+2.1 (gamma-Cygni) in hard X-ray energy bands from 25 keV to 120 keV are obtained with the IBIS-ISGRI imager aboard…
High-energy emission from the stellar wind collisions in gamma-2 Velorum
V. Tatischeff, R. Terrier, F. Lebrun
The binary system gamma-2 Velorum (WC8+O7.5) contains the nearest known Wolf-Rayet star to the Sun, at a distance of 258 pc. Its strong radio emission shows evidence…
