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…

Can Flat Spectrum Radio Quasars make most of the overall gamma--ray background ?
A. Comastri, T. Di Girolamo, G. Setti
The contribution of discrete sources to the gamma--ray background is modeled. Flat spectrum radio quasars are known to make a substantial contribution to the hard (E > 100 MeV) bac…
