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…
Radiatively inefficient accretion disks in Low Luminosity AGN
F. D. Macchetto, M. Chiaberge
We study a complete and distance-limited sample of 25 LINERs, 21 of which have been imaged with the Hubble Space Telescope to study their physical properties and to compare their r…
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…
