The Tidal Disruption Event AT 2018hyz I: Double-peaked emission lines and a flat Balmer decrement
P. Short, M. Nicholl, A. Lawrence +28
We present results from spectroscopic observations of AT 2018hyz, a transient discovered by the ASAS-SN survey at an absolute magnitude of mag, in the nucleus of a…
Universal bolometric corrections for AGN over 7 luminosity decades
F. Duras, A. Bongiorno, F. Ricci +12
The AGN bolometric correction is a key element to understand BH demographics and compute accurate BH accretion histories from AGN luminosities. However, current estimates still dif…
NGC 1275: an outlier of the black hole-host scaling relations
Eleonora Sani, Federica Ricci, Fabio La Franca +7
The active galaxy NGC 1275 lies at the center of the Perseus cluster of galaxies, being an archetypal BH-galaxy system that is supposed to fit well with the M_BH-host scaling relat…
Black hole masses of tidal disruption event host galaxies
Thomas Wevers, Sjoert van Velzen, Peter G. Jonker +5
The mass of the central black hole in a galaxy that hosted a tidal disruption event (TDE) is an important parameter in understanding its energetics and dynamics. We present the fir…
Detection of faint broad emission lines in type 2 AGN: III. On the relation of type 2 AGN
F. Ricci, F. La Franca, A. Marconi +10
Type 2 active galactic nuclei (AGN) represent the majority of the AGN population. However, due to the difficulties in measuring their black hole (BH) masses, it is still unknown wh…
Detection of faint broad emission lines in type 2 AGN: II. On the measurement of the BH mass of type 2 AGN and the unified model
F. Onori, F. Ricci, F. La Franca +8
We report the virial measurements of the BH mass of a sample of 17 type 2 AGN, drawn from the Swift/BAT 70-month 14-195 keV hard X-ray catalogue, where a faint BLR component has be…
Detection of faint broad emission lines in type 2 AGN: I. Near infrared observations and spectral fitting
F. Onori, F. La Franca, F. Ricci +8
We present medium resolution near infrared spectroscopic observations of 41 obscured and intermediate class AGN (type 2, 1.9 and 1.8; AGN2) with redshift 0.1, selected…
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…
Detection of Faint BLR Components in the Starburst/Seyfert Galaxy NGC 6221 and Measure of the Central BH Mass
Fabio La Franca, Francesca Onori, Federica Ricci +4
In the last decade, using single epoch virial based techniques in the optical band, it has been possible to measure the central black hole mass on large AGN1 samples. However these…
Extending Virial Black Hole Mass Estimates to Low-Luminosity or Obscured AGN: the cases of NGC 4395 and MCG -01-24-012
Fabio La Franca, Francesca Onori, Federica Ricci +8
In the last decade, using single epoch (SE) virial based spectroscopic optical observations, it has been possible to measure the black hole (BH) mass on large type 1 Active Galacti…
X-shooter reveals powerful outflows in z~1.5 X-ray selected obscured quasi stellar objects
M. Brusa, A. Bongiorno, G. Cresci +20
We present X-shooter at the Vewry Large Telescope observations of a sample of 10 luminous, X-ray obscured QSOs at z from the XMM-COSMOS survey, expected to be caught in th…
Simultaneous X-ray and optical observations of true Type 2 Seyfert galaxies
Stefano Bianchi, Francesca Panessa, Xavier Barcons +9
We present the results of a campaign of simultaneous X-ray and optical observations of `true' Type 2 Seyfert galaxies candidates, i.e. AGN without a Broad Line Region (BLR). Out of…
