On the nature of the hard X-ray source IGR J2018+4043
A. M. Bykov, A. M. Krassilchtchikov, Yu. A. Uvarov +13
We found a very likely counterpart to the recently discovered hard X-ray source IGR J2018+4043 in the multi-wavelength observations of the source field. The source, originally disc…
Imaging extended sources with coded mask telescopes: Application to the INTEGRAL IBIS/ISGRI instrument
Renaud Matthieu, Alexandra Gros, François Lebrun +4
Context. In coded mask techniques, reconstructed sky images are pseudo-images: they are maps of the correlation between the image recorded on a detector and an array derived from t…
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…
In flight calibration of the ISGRI camera
Regis Terrier, F. Lebrun, A. Bazzano +12
ISGRI, the IBIS low energy camera (15 keV - 1 MeV) on board INTEGRAL, is the first large CdTe gamma-ray imager in orbit. We present here an overview of the ISGRI in-flight calibrat…
Systematic effects induced on IBIS detectors by background and inhomogeneity of the spatial response
L. Natalucci, A. J. Bird, A. Bazzano +4
The spatial distribution of the background events may affect the source detection capability of IBIS at high energies (> 200 keV) for both ISGRI and PICsIT layers. The observed bac…
First Results from the IBIS/ISGRI Data Obtained During the Galactic Plane Scan. II. The Vela Region
J. Rodriguez, M. Del Santo, F. Lebrun +13
We report on INTEGRAL/IBIS observations of the Vela region during a Galactic Plane Scan (hereafter GPS) presenting the IBIS in-flight performances during these operations. Among al…
