Multi-wavelength and black hole mass properties of Low Luminosity Active Nuclei
F. Panessa, L. Bassani, M. Cappi +6
We investigate the relation between the X-ray nuclear emission, optical emission line, radio luminosity and black hole mass for a sample of nearby Seyfert galaxies. Strong linear c…
Search for relativistic beaming in ultraluminous X-ray sources
L. Foschini, G. Malaguti, G. Di Cocco +3
The nature of the ultraluminous X-ray sources (ULX) is still to be understood. Several hypotheses have been suggested to explain the high X-ray luminosity: stellar mass black holes…
XMM-NEWTON Observation of the Seyfert 2 Galaxy NGC 4138
L. Foschini, F. Panessa, A. L. Longinotti +9
The XMM-Newton data presented here are the first X-ray observation of the Seyfert 2 galaxy NGC4138. Although the galaxy has been pointed by ROSAT-HRI, it was not detected, with a f…
First Results from a XMM-Newton Survey of a Distance-Limited (D<22 Mpc) Sample of Seyfert Galaxies: I- the Agns
M. Cappi, G. Di Cocco, F. Panessa +18
We report here preliminary results from a survey of nearby Seyfert galaxies using the EPIC CCDs on board XMM-Newton. The total sample consists of 28 Seyfert galaxies, and constitut…
