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…
An XMM-Newton Study of Hard X-ray Sources
E. Piconcelli, L. Bassani, M. Cappi +3
We briefly report on an on-going spectroscopic study of hard X-ray sources selected serendipitously in 12 XMM-Newton fields. Results for the analysis of the 41 sources from the fir…
Flux and spectral variations in the Circinus Galaxy
S. Bianchi, G. Matt, F. Fiore +3
We report on a dramatic flux (50 % increase in the LECS and MECS band) and spectral variation between two BeppoSAX observations of the Circinus Galaxy performed almost three years…
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…
The HELLAS2XMM survey: II. Multiwavelength observations of P3: an X-ray bright, optically inactive galaxy
A. Comastri, M. Mignoli, P. Ciliegi +11
Recent X-ray surveys have clearly demonstrated that a population of optically dull, X-ray bright galaxies is emerging at 2-10 keV fluxes of the order of 10^{-14} erg cm^{-2} s^{-1}…
