Beyond the X-ray background with XEUS
A. Comastri, P. Ranalli, M. Brusa
We briefly discuss the perspectives of sensitive hard X-ray observations with the large collecting area X-ray telescopes of XEUS.
An XMM-Newton survey of Extremely Red Objects
M. Brusa, A. Comastri, E. Daddi +2
We present preliminary results of a 25 ks XMM-Newton observation of the largest sample of Extremely Red Objects (EROs) available to date (about 450 sources), selected in a contiguo…
On the nature of X-ray Bright Optically Normal galaxies
A. Comastri, M. Brusa, P. Ciliegi +10
Multiwavelength observations of the hard X-ray selected sources by Chandra and XMM-Newton surveys have significantly improved our knowledge of the objects responsible of the hard X…
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…
The 2-10 keV luminosity as a Star Formation Rate indicator
Piero Ranalli, Andrea Comastri, Giancarlo Setti
Radio and far infrared luminosities of star forming galaxies follow a tight linear relation. Making use of BeppoSAX and ASCA observations of a well-defined sample of star forming g…
