The nuclear accretion in the FR I radio galaxy IC4296 from CHANDRA and VLBA observations
S. Pellegrini, T. Venturi, A. Comastri +5
A high angular resolution study of the nucleus of the FR I galaxy IC4296 using Chandra ACIS-S and VLBA observations is presented, with the aim of studying the nature of the accreti…
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.
Extremely Red Objects: an X-ray dichotomy
M. Brusa, A. Comastri, E. Daddi +3
We analyze the X-ray properties of a near-infrared selected (Ks < 20) sample of spectroscopically identified Extremely Red Objects (R-Ks>5) in a region of the Chandra Deep Field-So…
The 2-10 keV luminosity as a Star Formation Rate indicator
P. Ranalli, A. Comastri, G. Setti
Radio and far infrared luminosities of star-forming galaxies follow a tight linear relation. Making use of ASCA and BeppoSAX observations of a well-defined sample of nearby star-fo…
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…
