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…
AGN STORM 2. VI. Mapping Temperature Fluctuations in the Accretion Disk of Mrk 817
Jack M. M. Neustadt, Christopher S. Kochanek, John Montano +49
We fit the UV/optical lightcurves of the Seyfert 1 galaxy Mrk 817 to produce maps of the accretion disk temperature fluctuations resolved in time and radius. The maps are…
AGN STORM 2. IV. Swift X-ray and ultraviolet/optical monitoring of Mrk 817
Edward M. Cackett, Jonathan Gelbord, Aaron J. Barth +48
The AGN STORM 2 campaign is a large, multiwavelength reverberation mapping project designed to trace out the structure of Mrk 817 from the inner accretion disk to the broad emissio…
AGN STORM 2. III. A NICER view of the variable X-ray obscurer in Mrk 817
Ethan R. Partington, Edward M. Cackett, Erin Kara +44
The AGN STORM 2 collaboration targeted the Seyfert 1 galaxy Mrk 817 for a year-long multiwavelength, coordinated reverberation mapping campaign including HST, Swift, XMM-Newton, NI…
AGN STORM 2: I. First results: A Change in the Weather of Mrk 817
Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69
We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…
On the multi-wavelength variability of Mrk 110: Two components acting at different timescales
F. M. Vincentelli, I. McHardy, E. M. Cackett +17
We present the first intensive continuum reverberation mapping study of the high accretion rate Seyfert galaxy Mrk 110. The source was monitored almost daily for more than 200 days…
The First Swift Intensive AGN Accretion Disk Reverberation Mapping Survey
R. Edelson, J. Gelbord, E. Cackett +32
Swift intensive accretion disk reverberation mapping of four AGN yielded light curves sampled 200-350 times in 0.3-10 keV X-ray and six UV/optical bands. Uniform reduction an…
Accretion disk reverberation with Hubble Space Telescope observations of NGC 4593: evidence for diffuse continuum lags
Edward M. Cackett, Chia-Ying Chiang, Ian McHardy +4
The Seyfert 1 galaxy NGC 4593 was monitored spectroscopically with the Hubble Space Telescope as part of a reverberation mapping campaign that also included Swift, Kepler and groun…
Swift monitoring of NGC 4151: Evidence for a Second X-ray/UV Reprocessing
R. Edelson, J. Gelbord, E. Cackett +41
Swift monitoring of NGC 4151 with ~6 hr sampling over a total of 69 days in early 2016 is used to construct light curves covering five bands in the X-rays (0.3-50 keV) and six in t…
