The Size-luminosity Relation of the AGN Torus Determined from the Comparison between Optical and Mid-infrared Variability

Minjin Kim, Suyeon Son, Luis C. Ho

We investigate the optical variability of low-redshift () active galactic nuclei using the multi-epoch data from the Zwicky Transient Facility. We find that a dampe…

The Reliability of Accretion Disk Inclination Derived from X-ray Spectroscopy of Active Galaxies

Rong Du, Yuanze Ding, Luis C. Ho +1

The inclination angle of substructures in active galaxies gives insights into physical components from scales of the vicinity of the central black hole to the entire host galaxy. W…

The Structure Function of Mid-infrared Variability in Low-redshift Active Galactic Nuclei

Suyeon Son, Minjin Kim, Luis C. Ho

Using the multi-epoch mid-infrared (MIR) photometry from the Wide-field Infrared Survey Explorer spanning a baseline of yr, we extensively investigate the MIR variability…

The destruction and recreation of the X-ray corona in a changing-look Active Galactic Nucleus

C. Ricci, E. Kara, M. Loewenstein +16

We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-…

The zCOSMOS Redshift Survey: evolution of the light in bulges and discs since z~0.8

L. A. M. Tasca, L. Tresse, O. Le Fevre +52

We studied the chronology of galactic bulge and disc formation by analysing the relative contributions of these components to the B-band rest-frame luminosity density at different…

High-ionization mid-infrared lines as black hole mass and bolometric luminosity indicators in active galactic nuclei

K. M. Dasyra, L. C. Ho, L. Armus +6

We present relations of the black hole mass and the optical luminosity with the velocity dispersion and the luminosity of the [Ne V] and the [O IV] high-ionization lines in the mid…
