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…
Supermassive black hole mass measurement in the spiral galaxy NGC 4736 Using JWST/NIRSpec stellar kinematics
Dieu D. Nguyen, Hai N. Ngo, Tinh Q. T. Le +12
We present accurate mass measurements of the central supermassive black hole (SMBH) in NGC 4736 (M 94).\ We used the ``gold-standard" stellar absorption features (CO band heads) at…
