ALMA Observations Show Major Mergers Among the Host Galaxies of Fast-growing, High-redshift Supermassive Black Holes
Benny Trakhtenbrot, Paulina Lira, Hagai Netzer +3
We present new ALMA band-7 data for a sample of six luminous quasars at z~4.8, powered by fast-growing supermassive black holes (SMBHs) with rather uniform properties: the typical…
The Complete Infrared View of Active Galactic Nuclei from the 70-month Swift/BAT Catalog
Kohei Ichikawa, Claudio Ricci, Yoshihiro Ueda +5
We systematically investigate the near- (NIR) to far-infrared (FIR) photometric properties of a nearly complete sample of local active galactic nuclei (AGN) detected in the Swift/B…
Optical variability of AGN in the PTF/iPTF survey
Neven Caplar, Simon J. Lilly, Benny Trakhtenbrot
We characterize the optical variability of quasars in the intermediate Palomar Transient Factory (iPTF) and Palomar Transient Factory (PTF) surveys. We re-calibrate the -band li…
On the Accretion Rates and Radiative Efficiencies of the Highest Redshift Quasars
Benny Trakhtenbrot, Marta Volonteri, Priyamvada Natarajan
We estimate the accretion rates onto the supermassive black holes that power 20 of the highest-redshift quasars, at z>5.8, including the quasar with the highest redshift known to d…
BAT AGN Spectroscopic Survey-III. An observed link between AGN Eddington ratio and narrow emission line ratios
Kyuseok Oh, Kevin Schawinski, Michael Koss +14
We investigate the observed relationship between black hole mass (), bolometric luminosity (), and Eddington ratio () with optical emission li…
The Chandra COSMOS Legacy Survey: Clustering of X-ray selected AGN at 2.9<z<5.5 using photometric redshift Probability Distribution Functions
V. Allevato, F. Civano, A. Finoguenov +16
We present the measurement of the projected and redshift space 2-point correlation function (2pcf) of the new catalog of Chandra COSMOS-Legacy AGN at 2.9z5.5 ($\langle…
Testing the Completeness of the SDSS Colour Selection for Ultramassive, Slowly Spinning Black Holes
Caroline Bertemes, Benny Trakhtenbrot, Kevin Schawinski +2
We investigate the sensitivity of the colour-based quasar selection algorithm of the Sloan Digital Sky Survey to several key physical parameters of supermassive black holes (SMBHs)…
Determining the radio AGN contribution to the radio-FIR correlation using the black hole fundamental plane relation
O. Ivy Wong, M. J. Koss, K. Schawinski +5
We investigate the 1.4 GHz radio properties of 92 nearby (z<0.05) ultra hard X-ray selected Active Galactic Nuclei (AGN) from the Swift Burst Alert Telescope (BAT) sample. Through…
Active galactic nuclei at z ~ 1.5: III. Accretion discs and black hole spin
Daniel M. Capellupo, Hagai Netzer, Paulina Lira +2
This is the third paper in a series describing the spectroscopic properties of a sample of 39 AGN at , selected to cover a large range in black hole mass () and…
Active galactic nuclei at z~1.5: II. Black Hole Mass estimation by means of broad emission lines
Julián E. Mejía-Restrepo, Benny Trakhtenbrot, Paulina Lira +2
This is the second in a series of papers aiming to test how the mass (), accretion rate () and spin () of super massive black holes (SMBHs) determine th…
