Search of sub-parsec massive binary black holes through line diagnosis
C. Montuori, M. Dotti, M. Colpi +2
We investigate on the spectral properties of an active black hole, member of a massive (10^7 - 10^9 Msun) sub-parsec black hole binary. We work under the hypothesis that the binary…
High redshift Fermi blazars
G. Ghisellini, G. Tagliaferri, L. Foschini +6
With the release of the first year Fermi catalogue, the number of blazars detected above 100 MeV lying at high redshift has been largely increased. There are 28 blazars at z>2 in t…
Chasing the heaviest black holes of jetted Active Galactic Nuclei
G. Ghisellini, R. Della Ceca, M. Volonteri +7
We investigate the physical properties of the 10 blazars at redshift greater than 2 detected in the 3-years all sky survey performed by the Burst Alert Telescope (BAT) onboard the…
High redshift formation and evolution of central massive objects I: model description
B. Devecchi, M. Volonteri, M. Colpi +1
Galactic nuclei host central massive objects either in the form of supermassive black holes or nuclear stellar clusters. Recent investigations have shown that both components co-ex…
