Dynamical Modelling of Galactic Kinematics using Neural Networks
David A. Simon, Michele Cappellari, Shude Mao +2
The advent of integral field data has revolutionised the study of galaxy evolution. A key component of this is dynamical modelling methods which have allowed for crucial insights t…
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…
When relics were made: vigorous stellar rotation and low dark matter content in the massive ultra-compact galaxy GS-9209 at z=4.66
Robert G. Pascalau, Francesco D'Eugenio, Sandro Tacchella +24
JWST uncovered a large number of massive quiescent galaxies (MQGs) at , which theoretical models struggle to reproduce. Explaining the number density of such objects requires…
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…
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…
PowerBin: Fast Adaptive Data Binning with Centroidal Power Diagrams
Michele Cappellari
Adaptive binning is a crucial step in the analysis of large astronomical datasets, such as those from integral-field spectroscopy, to ensure a sufficient signal-to-noise ratio (S/N…
