Geometry and inclination of the broad line region in blazars
Roberto Decarli, Massimo Dotti, Aldo Treves
We study the properties of the broad line region in blazars by comparing the virial estimate of black hole masses with that derived from the mass of the host galaxies. The former i…
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…
The peculiar optical spectrum of 4C+22.25: Imprint of a massive black hole binary?
Roberto Decarli, Massimo Dotti, Carmen Montuori +2
We report the discovery of peculiar features in the optical spectrum of 4C+22.25, a flat spectrum radio quasar at z=0.4183 observed in the SDSS and in a dedicated spectroscopic fol…
A quasar companion to the puzzling quasar SDSS J0927+2943
R. Decarli, R. Falomo, A. Treves +1
We report the discovery of a quasar close to SDSS J0927+2943 (z = 0.713), which is a massive binary / recoiling black hole candidate. The companion quasar is at a projected distanc…
