The X-ray emission of the most luminous 3CR radio sources

M. Salvati, G. Risaliti, P. Veron +1

We investigate the X-ray properties of the most luminous radio sources in the 3CR catalogue, in order to assess if they are similar to the most luminous radio quiet quasars, for in…

The optical emission line spectrum of Mark 110

M. -P. Veron-Cetty, P. Veron, M. Joly +1

We analyse in detail the rich emission line spectrum of Mark 110 to determine the physical conditions in the nucleus of this object, a peculiar NLS1 without any detectable Fe II em…

The emission spectrum of the strong Fe II emitter BAL Seyfert 1 galaxy IRAS 07598+6508

M. -P. Veron, M. Joly, P. Veron +3

The narrow-line Seyfert 1 galaxy IRAS 07598+6508 is known to be a stong Fe II emitter. The analysis of several high S/N ratio spectra shows that its spectrum is dominated by a rela…

The unusual emission line spectrum of IZw1

M. -P. Veron-Cetty, M. Joly, P. Veron

Most Seyfert 1s show strong Fe II lines in their spectrum having the velocity and width of the broad emission lines. To remove the Fe II contribution in these objects, an accurate…

Optically bright Active Galactic Nuclei in the ROSAT-Faint Source Catalogue

M. -P. Veron-Cetty, S. K. Balayan, A. M. Mickaelian +8

To build a large, optically bright, X-ray selected AGN sample we have correlated the ROSAT-FSC catalogue of X-ray sources with the USNO catalogue limited to objects brighter than O…

The "red shelf" of the Hb line in the Seyfert 1 galaxies RXS J01177+3637 and HS 0328+05

P. Veron, A. C. Goncalves, M. -P. Veron-Cetty

A few Seyfert 1s have a Hb profile with a red wing usually called the "red shelf". The most popular interpretation of this feature is that it is due to broad redshifted lines of Hb…
