HD97048: a closer look to the disk
Doucet, C., Habart +11
Aims: Today, large ground-based instruments, like VISIR on the VLT, providing diffraction-limited (about 0.3 arcsec) images in the mid-infrared where strong PAH features appear ena…
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…
Reflection at large distance from the central engine in Seyfert 1s
Julien Malzac, Pierre-Olivier Petrucci
We consider the possibility that most of the reflection component, observed in the hard X-ray spectra of Seyfert galaxies, could be formed on an extended medium, at large distance…
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…
