Novel calibrations of virial black hole mass estimators in active galaxies based on X-ray luminosity and optical/NIR emission lines
F. Ricci, F. La Franca, F. Onori +1
Accurately weigh the masses of SMBH in AGN is currently possible for only a small group of local and bright broad-line AGN through reverberation mapping (RM). Statistical demograph…
The XXL survey: first results and future
M. Pierre, C. Adami, M. Birkinshaw +108
The XXL survey currently covers two 25 sq. deg. patches with XMM observations of ~10ks. We summarise the scientific results associated with the first release of the XXL data set, t…
Optical archival spectra of blazar candidates of uncertain type in the 3 Fermi Large Area Telescope Catalog
N. Álvarez Crespo, F. Massaro, R. D'Abrusco +10
Despite the fact that blazars constitute the rarest class among active galactic nuclei (AGNs) they are the largest known population of associated -ray sources. Many of the -r…
Optical Spectroscopic Observations of Gamma-ray Blazar Candidates. V. TNG, KPNO, and OAN Observations of Blazar Candidates of Uncertain Type in the Northern Hemisphere
N. Álvarez Crespo, N. Masetti, F. Ricci +12
The extragalactic -ray sky is dominated by emission from blazars, a peculiar class of active galactic nuclei (AGNs). Many of the -ray sources included in Fermi -Large Area Te…
