Galactic Morpholography: Linking present-day galaxy compactness to assembly history and relic formation in the COLIBRE simulations
Maximilian Zemsch, Claudia D. P. Lagos, Chiara Spiniello +11
Compactness is widely used to identify candidate relic galaxies, the largely untouched survivors of the first compact massive galaxies. Yet relicness is an evolutionary rather than…
Stochastic black hole growth tracks stellar mass in ultramassive galaxies
Michele Cappellari, Dieu D. Nguyen, Susan A. Kassin
Over the past three decades, it has been established that galaxy spheroids contain supermassive black holes (BHs) whose masses correlate tightly with the properties of their host g…
The JWST Ultramassive Galaxy Sample -- II. Supermassive Black Hole Masses for 8 Extreme Early-Type Galaxies via Jeans Anisotropic Modelling of High-Resolution Integral-Field NIRSpec Stellar Kinematics
Michele Cappellari, Dieu D. Nguyen, Susan A. Kassin
We present central supermassive black hole (BH) mass measurements for the JWST Ultramassive Galaxy Sample, comprising 8 galaxies selected from a complete sample of the most massive…
The JWST Ultramassive Galaxy Sample -- I. Overview, Photometry, and Stellar Kinematics: Selecting Optimal Template Subsets via Non-Negative Matrix Factorization
Michele Cappellari, Dieu D. Nguyen, Susan A. Kassin
We introduce the JWST Ultramassive Galaxy Sample, comprising 8 extreme early-type galaxies () drawn as a representative subset fro…
KiDS J1447-0149: The first spatially resolved spectroscopy of a relic galaxy beyond the local universe. An old high-dispersion core embedded in a compact rotating stellar structure
Johanna Hartke, Chiara Spiniello, Michele Cappellari +13
Relic galaxies are the descendants of high-redshift compact quiescent systems. We present the first spatially resolved spectroscopic study of J1447-0149, a massive relic at $z=0.21…
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…
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…
