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…

Spatially Resolved [O III] Emission Line Kinematics of Reverberation-Mapped AGNs with the Keck Cosmic Web Imager

Raymond P. Remigio, Vivian U, Aaron J. Barth +8

We present optical integral-field spectroscopic data of ten nearby () Seyfert 1 galaxies taken with the Keck Cosmic Web Imager (KCWI). We map the spatially re…

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…

Testing X-ray Reprocessing and Mapping the Soft Excess of NGC 7469 with NICER

Ethan R. Partington, Edward M. Cackett, Rick Edelson +5

We present an X-ray/UV reverberation analysis of NGC 7469 across 210 days, using daily NICER observations with contemporaneous monitoring by Swift UVOT+XRT. We model the X-ray spec…
