ALMA CO(2-1) Gas Dynamics in NGC 315: A Multi-Method Benchmark for Supermassive Black Hole Mass Measurement
Dieu D. Nguyen, Benjamin D. Boizelle, Hai N. Ngo +11
We present ALMA Cycle~7 \cotwo\ observations of the circumnuclear disk in NGC~315 at an angular resolution of $0\farcs230\times0\farcs175$, improving on past measurements and resol…

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…

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-…
