Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
IGR J19140+098, a new INTEGRAL transient
Juho Schultz, Diana C. Hannikainen, Osmi Vilhu +5
IGR J19140+098 (SIMBAD corrected name IGR J19140+0951) is a new X-ray transient, discovered by INTEGRAL during an observation of GRS 1915+015. The source presents strong variations…
INTEGRAL observations of the transient source IGR J19140+098
C. Cabanac, J. Rodriguez, P. O Petrucci +3
IGR J19140+098 was discovered during the early INTEGRAL observations of GRS1915+105 in March 2003. The following observations by INTEGRAL and RXTE show significant variability on v…
Pair Creation at Shocks: Application to Agns
P. O. Petrucci, G. Henri, G. Pelletier
We investigate the effect of pair creation on a shock structure. Actually, particles accelerated by a shock can be sufficiently energetic to boost, via Inverse Compton process for…
Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
Anisotropic Illumination in AGNs. The reflected component. Comparison to hard X-ray spectra from Seyfert Galaxies
J. Malzac, E. Jourdain, P. O. Petrucci +1
We calculate the reflection component predicted by the anisotropic illumination model of Henri & Petrucci 1997. This component appears to be more important than for isotropic model…
