The optical-UV spectral energy distribution of the unabsorbed AGN population in the XMM-Newton Bright Serendipitous Survey
E. Marchese, R. Della Ceca, A. Caccianiga +3
Active galactic nuclei (AGN) emit radiation over a wide range of wavelengths, with a peak of emission in the far-UV region of the electromagnetic spectrum, a spectral region that i…
The Intracluster Plasma: a Universal Pressure Profile?
A. Lapi, A. Cavaliere, R. Fusco-Femiano
The pressure profiles of the Intracluster Plasma in galaxy clusters show a wide variance when observed in X rays at low redshifts z<0.2. We find the profiles to follow two main pat…
Accurate classification of 28 objects detected in the 39 months Palermo Swift/BAT hard X-ray catalogue
P. Parisi, N. Masetti, E. Jiménez-Bailón +12
Through an optical campaign performed at 4 telescopes located in the northern and the southern hemispheres, plus archival data from two on-line sky surveys, we have obtained optica…
Environmental effects in the interaction and merging of galaxies in zCOSMOS
P. Kampczyk, S. J. Lilly, L. de Ravel +56
(Abridged) We analyze the environments and galactic properties (morphologies and star-formation histories) of a sample of 153 close kinematic pairs in the redshift range 0.2 < z <…
Broadband X-ray properties of absorbed AGN
A. De Rosa, F. Panessa, L. Bassani +6
In this paper we report on the broadband X-ray properties of a complete sample of 33 absorbed Seyfert galaxies hard X-ray selected with integral. The high quality broadband spectra…
Observational evidence of quasar feedback quenching star formation at high redshift
M. Cano-Diaz, R. Maiolino, A. Marconi +3
Most galaxy evolutionary models require quasar feedback to regulate star formation in their host galaxies. In particular, at high redshift, models expect that feedback associated w…
