Dynamical Evidence for a Billion Solar Mass Black Hole in Galaxy NGC 4061 from ALMA CO(2-1) Kinematics
Dieu D. Nguyen, Long Q. T. Nguyen, Elena Gallo +6
We present the first robust dynamical measurement of the supermassive black hole (SMBH) mass in the massive early-type galaxy NGC 4061 using high-spatial-resolution ALMA observatio…
The Supermassive Black Hole in the Nearby Spiral Galaxy M81: A Robust Mass from JWST/NIRSpec Stellar Dynamics
Dieu D. Nguyen, Tuan N. Le, Michele Cappellari +9
Despite its proximity, the mass of the supermassive black hole (SMBH) in the spiral galaxy M81 (NGC~3031) has remained uncertain, with previous dynamical measurements being unrelia…
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…
Detecting Intermediate-Mass Black Holes out to 20 Mpc with ELT/HARMONI: The Case of FCC 119
Hai N. Ngo, Dieu D. Nguyen, Tinh T. Q. Le +3
Intermediate-mass black holes (IMBHs; ) play a critical role in understanding the formation of supermassive black holes in the early universe. In t…
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…
