Supermassive Black Hole Winds in X-rays -- SUBWAYS. III. A population study on ultra-fast outflows
V. E. Gianolli, S. Bianchi, P-O Petrucci +44
The detection of blue-shifted absorption lines likely associated with ionized Iron K-shell transitions in the X-ray spectra of many Active Galactic Nuclei (AGN) suggests the presen…
Euclid preparation. Spectroscopy of active galactic nuclei with NISP
Euclid Collaboration, E. Lusso, S. Fotopoulou +246
The statistical distribution and evolution of key properties (e.g. accretion rate, mass, or spin) of active galactic nuclei (AGN), remain an open debate in astrophysics. The ESA Eu…
Optical spectroscopic observations of low-energy counterparts of Fermi-LAT gamma-ray sources
H. A. Peña-Herazo, R. A. Amaya-Almazán, F. Massaro +15
A significant fraction of all -ray sources detected by the Large Area Telescope aboard the \fer\ satellite is still lacking a low-energy counterpart. In addition, there is still…
The 3CR extragalactic survey at high redshift
A. Jimenez-Gallardo, F. Massaro, M. A. Prieto +13
We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with during Cycle 20 in the redshift range between 1.5 and 2…
Optical spectroscopic observations of gamma-ray blazar candidates. IX. Optical archival spectra and further observations from SOAR and OAGH
H. A. Peña-Herazo, F. Massaro, V. Chavushyan +11
Nearly one-third of the sources in the -LAT catalogs lack a lower energy counterpart, hence being referred as unidentified/unassociated gamma-ray sources (UGSs). In order to…
BAT AGN Spectroscopic Survey -- XV: The High Frequency Radio Cores of Ultra-hard X-ray Selected AGN
Krista Lynne Smith, Richard F. Mushotzky, Michael Koss +14
We have conducted 22 GHz radio imaging at 1" resolution of 100 low-redshift AGN selected at 14-195 keV by the Swift-BAT. We find a radio core detection fraction of 96%, much higher…
BAT AGN Spectroscopic Survey -- XIX: Type 1 versus Type 2 AGN dichotomy from the point of view of ionized outflows
A. F. Rojas, E. Sani, I. Gavignaud +18
We present a detailed study of ionized outflows in a large sample of ~650 hard X-ray detected AGN. Using optical spectroscopy from the BAT AGN Spectroscopic Survey (BASS) we are ab…
Stormy weather in 3C 196.1: nuclear outbursts and merger events shape the environment of the hybrid radio galaxy 3C 196.1
F. Ricci, L. Lovisari, R. P. Kraft +8
We present a multi-wavelength analysis based on archival radio, optical and X-ray data of the complex radio source 3C 196.1, whose host is the brightest cluster galaxy of a $z=0.19…
The 3CR extragalactic survey at 1.01.5
C. Stuardi, V. Missaglia, F. Massaro +11
The aim of this paper is to present an analysis of newly acquired X-ray observations of 16 extragalactic radio sources, listed in the Third Cambridge Revised (3CR) catalog, and not…
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/VIRGO GW170817. III. Optical and UV Spectra of a Blue Kilonova From Fast Polar Ejecta
M. Nicholl, E. Berger, D. Kasen +31
We present optical and ultraviolet spectra of the first electromagnetic counterpart to a gravitational wave (GW) source, the binary neutron star merger GW170817. Spectra were obtai…
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…
