Continuum Reverberation Mapping of 18 AGN Over Four Years
Jake A. Miller, Edward M. Cackett, Misty C. Bentz +3
Continuum reverberation mapping probes the size scale of the optical continuum-emitting region in active galactic nuclei (AGN). The source of this emission has long been thought to…
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…
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…
Exploring Quasar Variability With ZTF at 0<z<3: A Universal Relation with Eddington Ratio
Hygor B. Gonçalves, Swayamtrupta Panda, Thaisa Storchi Bergmann +2
Quasars, powered by accretion onto supermassive black holes (SMBHs), exhibit significant variability, offering insights into the physics of accretion and the properties of the cent…
