Untangling the Complex Nature of AGN Variability with Fairall 9
Scott Hagen, Chris Done, Edward M. Cackett +5
The accretion flow in AGN is not well understood, motivating intensive monitoring campaigns of multiwavelength variability to probe its structure. One of the best of these is the 3…

The Accretion Disk Size Problem in AGN Disk Reverberation Mapping is an Obscuration Effect: A Uniform AGN Sample Study with Swift
Collin Lewin, Erin Kara, Christos Panagiotou +5
In the past decade, Swift has performed several AGN high-cadence reverberation mapping campaigns, and generally found that the UV/optical interband lags are 3 times longer th…

Effects of ultra-fast outflows on X-ray time lags in AGN
Yerong Xu, Ciro Pinto, Erin Kara +3
The time lag between soft and hard X-ray photons has been observed in many active galactic nuclei (AGN) and can reveal the accretion process and geometry around supermassive black…
