Intensive broadband reverberation mapping of Fairall 9 with 1.8 years of daily Swift monitoring

R. Edelson, B. M. Peterson, J. Gelbord +5

We present 1.8 years of near-daily Swift monitoring of the bright, strongly variable Type 1 AGN Fairall 9. Totaling 575 successful visits, this is the largest such campaign reporte…

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…

Dust Reverberation Mapping and Light-Curve Modelling of Zw229-015

E. Guise, S. F. Hönig, V. Gorjian +12

Multiwavelength variability studies of active galactic nuclei (AGN) can be used to probe their inner regions which are not directly resolvable. Dust reverberation mapping (DRM) est…

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…
