Intensive X-ray/UVOIR continuum reverberation mapping of the Seyfert AGN MCG+08-11-11

D. Kynoch, I. M. McHardy, E. M. Cackett +11

We present results from intensive (x3 daily), three-month-long X-ray, UV and optical monitoring of the bright Seyfert active galactic nucleus (AGN) MCG+08-11-11 with Swift, support…

AGN STORM 2. XI. Spectroscopic reverberation mapping of the hot dust in Mrk 817

Hermine Landt, Benjamin D. Boizelle, Michael S. Brotherton +41

The AGN Space Telescope and Optical Reverberation Mapping 2 (STORM 2) campaign targeted Mrk 817 with intensive multi-wavelength monitoring and found its soft X-ray emission to be s…

Departures from Standard Disk Predictions in Intensive Ground-Based Monitoring of Three AGN

Diego Gonzalez-Buitrago, Aaron J. Barth, Rick Edelson +42

We present ground-based, multi-band light curves of the AGN Mrk~509, NGC\,4151, and NGC\,4593 obtained contemporaneously with \sw\, monitoring. We measure cross-correlation lags re…

Continuum Reverberation Mapping of Accretion Disks Surrounding Supermassive Black Hole Binaries: Observational Signatures

Yi-Xin Fu, Yan-Rong Li, Jian-Min Wang +9

It has remained challenging to reliably identify sub-parsec supermassive black hole binaries (SMBHBs), despite them being expected to be ubiquitous. We propose a new method using m…

Echo mapping of the black hole accretion flow in NGC 7469

Raj Prince, Juan V. Hernández Santisteban, Keith Horne +20

Reverberation mapping (RM) can measure black hole accretion disc sizes and radial structure through observed time lags that should increase with wavelength as . Ou…
