A Phenomenological Study of the Accretion Disk in the Super-Eddington AGN I Zw 1
Farin Drewes, Roberta Vieliute, Juan V. Hernández Santisteban +11
The structure of the accretion disk in AGN is still an unsolved question, especially how it may change with Eddington ratio. Here we examine the accretion disk in the super-Eddingt…
Genuine Retrieval of the AGN Host Stellar Population (GRAHSP)
Johannes Buchner, Hattie Starck, Mara Salvato +11
The assembly and co-evolution of supermassive black holes (SMBH) and their host galaxy stellar population is a key open questions in galaxy evolution. Stellar mass () and…
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…
Disk winds spectral energy distribution and the variability timescale of active galactic nuclei
Hagai Netzer
Accretion disk winds are commonly observed in active galactic nuclei (AGN). The winds may be associated with the changing spectral properties of such sources, yet such connections…
