Long-term variability of AGN at hard X-rays
S. Soldi, V. Beckmann, W. H. Baumgartner +6
Variability at all observed wavelengths is a distinctive property of AGN. Hard X-rays provide us with a view of the innermost regions of AGN, mostly unbiased by absorption along th…
INTEGRAL IBIS/ISGRI energy calibration in OSA 10
I. Caballero, J. A. Zurita Heras, F. Mattana +7
We present the new energy calibration of the ISGRI detector onboard INTEGRAL, that has been implemented in the Offline Scientific Analysis (OSA) version 10. With the previous OSA 9…
The IBIS / ISGRI Source Location Accuracy
A. Gros, A. Goldwurm, S. Soldi +4
We present here results on the source location accuracy of the INTEGRAL IBIS/ISGRI coded mask telescope, based on ten years of INTEGRAL data and on recent developments in the data…
In-flight calibration of the INTEGRAL/IBIS mask
S. Soldi, F. Lebrun, A. Gros +9
Since the release of the INTEGRAL Offline Scientific Analysis (OSA) software version 9.0, the ghost busters module has been introduced in the INTEGRAL/IBIS imaging procedure, leadi…
Gamma-ray emitting radio galaxies at hard X-rays: Seyfert core or jet emission?
V. Beckmann, S. de Jong, F. Mattana +2
A number of radio galaxies has been detected by Fermi/LAT in the gamma-ray domain. In some cases, like Cen A and M 87, these objects have been seen even in the TeV range by Cherenk…
