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: V. Anomalous Behavior of the CIV Light Curve in Mrk 817

Y. Homayouni, Gerard A. Kriss, Gisella De Rosa +49

An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant vari…

Continuum Reverberation Mapping of Mrk 876 Over Three Years With Remote Robotic Observatories

Jake A. Miller, Edward M. Cackett, Michael R. Goad +9

Continuum reverberation mapping probes the sizescale of the optical continuum-emitting region in active galactic nuclei (AGN). Through 3 years of multiwavelength photometric monito…

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: II. Ultraviolet Observations of Mrk817 with the Cosmic Origins Spectrograph on the Hubble Space Telescope

Y. Homayouni, Gisella De Rosa, Rachel Plesha +62

We present reverberation mapping measurements for the prominent ultraviolet broad emission lines of the active galactic nucleus Mrk817 using 165 spectra obtained with the Cosmic Or…

UV/Optical disk reverberation lags despite a faint X-ray corona in the AGN Mrk 335

Erin Kara, Aaron J. Barth, Edward M. Cackett +37

We present the first results from a 100-day Swift, NICER and ground-based X-ray/UV/optical reverberation mapping campaign of the Narrow-Line Seyfert 1 Mrk 335, when it was in an un…
