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…
The nature of the multi-wavelength emission of 3C 111
S. de Jong, V. Beckmann, F. Mattana
We attempt to determine the nature of the high energy emission of the radio galaxy 3C 111, by distinguishing between the effects of the thermal and non-thermal processes. We study…
