Precision near-IR spectroscopy for understanding AGN physics and shed light on the H0 tension -- SHARP Science Book

M. Signorini, V. N. Bennert, E. Dalla Bontà +3

The persistent tension between early- and late-Universe measurements of the Hubble constant (H0) remains on of the most significant challenges in modern cosmology. The Spectroastro…

Can BLR line profile shape improve single-epoch black hole mass estimates?

Lizvette Villafaña, Tommaso Treu, Shu Wang +7

The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…

The Host Galaxies of Active Galactic Nuclei with Direct Black Hole Mass Measurements

Vardha N. Bennert, Nico Winkel, Tommaso Treu +13

Reverberation mapping (RM) determines the mass of black holes (BH) in active galactic nuclei (AGNs) by resolving the BH gravitational sphere of influence in the time domain. Recent…

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…

Seoul National University AGN Monitoring Project. V. Velocity-resolved H-beta Reverberation Mapping and Evidence of Kinematics Evolution

Shu Wang, Jong-Hak Woo, Aaron J. Barth +13

We present velocity-resolved reverberation lags of H-beta for 20 active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project. We detect unambiguous velo…
