The evolution of the heaviest super-massive black-holes in jetted AGNs
Alessandro Diana, Alessandro Caccianiga, Alberto Moretti +3
We present the space density evolution, from z=1.5 up to z=5.5, of the most massive (MM) black holes hosted in jetted Active Galactic Nuclei(AGNs). The analysis…

X-ray properties of z>4 blazars
L. Ighina, A. Caccianiga, A. Moretti +4
We present the X-ray analysis of the largest flux-limited complete sample of blazar candidates at z>4 selected from the Cosmic Lens All Sky Survey (CLASS). After obtaining a nearly…

Swift data hint at a binary Super Massive Black Hole candidate at sub-parsec separation
P. Severgnini, C. Cicone, R. Della Ceca +10
Dual/binary Supermassive Black Hole (SMBH) systems are the inevitable consequence of the current Lambda Cold Dark Matter cosmological paradigm. In this context, we discuss here the…
