Extending the Frontier of Spatially-Resolved Supermassive Black Hole Mass Measurements to at : Simulations with ELT/MICADO High-Resolution Mass Models and HARMONI Integral-Field Stellar Kinematics

Dieu D. Nguyen, Michele Cappellari, Tinh Q. T. Le +8

Current spatially resolved kinematic measurements of supermassive black hole (SMBH) masses are largely confined to the local Universe (distances Mpc). We investigate…

Central Massive Black Holes Are Not Ubiquitous in Local Low-Mass Galaxies

Fan Zou, Elena Gallo, Anil C. Seth +13

The black-hole occupation fraction () defines the fraction of galaxies that harbor central massive black holes (MBHs), irrespective of their accretion activity leve…

Revisiting the supermassive black hole mass of NGC 7052 using high spatial resolution molecular gas observed with ALMA

Hai N. Ngo, Dieu D. Nguyen, Tinh Q. T. Le +9

We present our dynamical mass constraints on the central supermassive black hole (SMBH) in the early-type galaxy NGC 7052 using high spatial-resolution observations of CO(2-…

Measuring the Central Dark Mass in NGC 4258 with JWST/NIRSpec Stellar Kinematics

Dieu D. Nguyen, Hai N. Ngo, Michele Cappellari +8

We present a new stellar dynamical measurement of the supermassive black hole (SMBH) mass in the nearby spiral galaxy NGC 4258, a critical benchmark for extragalactic mass measurem…

The X-ray Link Between High Eddington Ratio Dust-Obscured Galaxies (DOGs) and Hot DOGs

Fan Zou, W. N. Brandt, Elena Gallo +2

Dust-obscured galaxies (DOGs) with extremely red optical-to-infrared colors are often associated with intense starburst and AGN activity. Studying DOGs can provide insights into th…

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…
