A. Corral, M. J. Page, F. J. Carrera +7
One of the most important parameters in the XRB (X-ray background) synthesis models is the average efficiency of accretion onto SMBH (super-massive black holes). This can be inferr…

An XMM-Newton study of Hyper-Luminous Infrared Galaxies
A. Ruiz, F. J. Carrera, F. Panessa
Hyper-Luminous Infrared Galaxies (HLIRGs) are the most luminous persistent objects in the Universe. They exhibit extremely high star formation rates, and most of them seem to harbo…
