WFPC2 LRF Imaging of Emission Line Nebulae in 3CR Radio Galaxies
G. C. Privon, C. P. O'Dea, S. A. Baum +5
We present HST/WFPC2 Linear Ramp Filter images of high surface brightness emission lines (either [OII], [OIII], or H-alpha+[NII]) in 80 3CR radio sources. We overlay the emission l…
XMM-Newton broad-band observations of NGC 7582: Nh variations and fading out of the active nucleus
E. Piconcelli, S. Bianchi, M. Guainazzi +2
We present results from two XMM-Newton observations of the bright classical Seyfert 2 galaxy NGC 7582 taken four years apart (2001 May and 2005 April). We present the analysis of t…
Low radiative efficiency accretion at work in active galactic nuclei: the nuclear spectral energy distribution of NGC4565
M. Chiaberge, R. Gilli, F. D. Macchetto +1
We derive the spectral energy distribution (SED) of the nucleus of the Seyfert galaxy NGC4565. Despite its classification as a Seyfert2, the nuclear source is substantially unabsor…
The Warped Nuclear Disk of Radio Galaxy 3C 449
Grant R. Tremblay, Alice C. Quillen, David J. E. Floyd +11
Among radio galaxies containing nuclear dust disks, the bipolar jet axis is generally observed to be perpendicular to the disk major axis. The FR I radio source 3C 449 is an outlie…
A search for changing-look AGN in the Grossan catalog
S. Bianchi, M. Guainazzi, G. Matt +4
We observed with XMM-Newton 4 objects selected from the Grossan catalog, with the aim to search for new 'changing-look' AGN. The sample includes all the sources which showed in sub…
Investigating the EGRET-radio galaxies link with INTEGRAL: the case of 3EG J1621+8203 and NGC 6251
L. Foschini, M. Chiaberge, P. Grandi +10
The analysis of an INTEGRAL AO2 observation of the error contours of the EGRET source 3EG J1621+8203 is presented. The only source found inside the error contours for energies betw…
