Reverberation mapping of Active Galactic Nuclei: from X-ray corona to dusty torus
Edward M. Cackett, Misty C. Bentz, Erin Kara
The central engines of Active Galactic Nuclei (AGNs) are powered by accreting supermassive black holes, and while AGNs are known to play an important role in galaxy evolution, the…
Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies
Michael McDonald, Brian R. McNamara, Michael S. Calzadilla +5
We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live a…
Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548
P. R. Williams, A. Pancoast, T. Treu +155
We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…
X-ray fluorescence from super-Eddington accreting black holes
Lars Lund Thomsen, Jane Lixin Dai, Enrico Ramirez-Ruiz +2
X-ray reverberation has proven to be a powerful tool capable of probing the innermost region of accretion disks around compact objects. Current theoretical effort generally assumes…
1ES 1927+654: An AGN Caught Changing Look on a Timescale of Months
Benny Trakhtenbrot, Iair Arcavi, Chelsea L. MacLeod +21
We study the sudden optical and ultraviolet (UV) brightening of 1ES 1927+654, which until now was known as a narrow-line active galactic nucleus (AGN). 1ES 1927+654 was part of the…
A new class of flares from accreting supermassive black holes
Benny Trakhtenbrot, Iair Arcavi, Claudio Ricci +26
Accreting supermassive black holes (SMBHs) can exhibit variable emission across the electromagnetic spectrum and over a broad range of timescales. The variability of active galacti…
