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…

Gravitational Torques from a Lopsided Young Stellar Component Sustain High Black Hole Accretion Rates in NGC 4593

Nico Winkel, Knud Jahnke, Juan Antonio Fernández-Ontiveros +8

Supermassive black holes (SMBHs) grow primarily through gas accretion, observed as active galactic nuclei (AGNs). While mergers can drive luminous AGN episodes, secular processes m…

The Close AGN Reference Survey (CARS): A comparison between sub-mm and optical AGN diagnostic diagrams

Jacob S. Elford, Timothy A. Davis, Ilaria Ruffa +9

The relation suggests that there is a tight connection between dense gas and star formation. We use data from the Close AGN Reference Survey (CARS) to inve…

The Close AGN Reference Survey (CARS). Long-term spectral variability study of the changing look AGN Mrk 1018

T. Saha, M. Krumpe, A. Markowitz +9

Changing-look AGNs (CLAGN) are accreting supermassive black hole systems that undergo variations in optical spectral type, driven by major changes in accretion rate. Mrk 1018 has u…

Combining Direct Black Hole Mass Measurements and Spatially Resolved Stellar Kinematics to Calibrate the - Relation of Active Galaxies

Nico Winkel, Vardha N. Bennert, Raymond P. Remigio +8

The origin of the tight scaling relation between the mass of supermassive black holes (SMBHs; ) and their host-galaxy properties remains unclear. Active galactic nuclei…
