AGN STORM 2. XII. Ground-Based Optical Photometry and Lag Measurements of Mrk 817
John W. Montano, Aaron J. Barth, Keith Horne +40
We present the ground-based imaging campaign and light curves of Markarian 817 as part of the multiwavelength monitoring program AGN STORM\,2. Observations were carried out over 1.…
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…
Testing X-ray Reprocessing and Mapping the Soft Excess of NGC 7469 with NICER
Ethan R. Partington, Edward M. Cackett, Rick Edelson +5
We present an X-ray/UV reverberation analysis of NGC 7469 across 210 days, using daily NICER observations with contemporaneous monitoring by Swift UVOT+XRT. We model the X-ray spec…
Connecting the X-ray/UV variability of Fairall 9 with NICER: A Possible Warm Corona
Ethan R. Partington, Edward M. Cackett, Rick Edelson +7
The Seyfert 1 AGN Fairall 9 was targeted by NICER, Swift, and ground-based observatories for a 1000-day long reverberation mapping campaign. The following analysis of NICER s…
AGN STORM 2. VII. A Frequency-resolved Map of the Accretion Disk in Mrk 817: Simultaneous X-ray Reverberation and UVOIR Disk Reprocessing Time Lags
Collin Lewin, Erin Kara, Aaron J. Barth +35
X-ray reverberation mapping is a powerful technique for probing the innermost accretion disk, whereas continuum reverberation mapping in the UV, optical, and infrared (UVOIR) revea…
