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…
Revealing AGN by Polarimetry
Makoto Kishimoto, Robert Antonucci, Catherine Boisson +1
Polarimetric study in the UV and optical has been one of the keys to reveal the structure and nature of active galactic nuclei (AGN). Combined with the HST's high spatial resolutio…
The Shape of the Big Blue Bump as Revealed by Spectropolarimetry
R. Antonucci, M. Kishimoto, C. Boisson +1
Thermal models for the quasar Big Blue Bump generally lead to bound-free continuum features, which may be in absorption or emission. Searches for Lyman edges attributable to quasar…
A kinematical analysis of NGC 2992
I. Marquez, C. Boisson, F. Durret +1
We present long slit spectroscopy for the [OIII] and H wavelength ranges along nine different position angles for the Sa Seyfert 1.9 galaxy NGC 2992. Double profiles are present…
A first look at galaxies with the DENIS survey
Gary Mamon, Vincent Banchet, Catherine Boisson +2
We review the various steps for the extraction of extended sources, principally galaxies, from the DENIS images. The capabilities of DENIS are studied with simulated images. A few…
