A spectroscopic map of the Galactic centre: Integrated light and dynamical modelling
A. Feldmeier-Krause, T. I. Maindl, G. van de Ven +3
The centre of the Milky Way is occupied by a nuclear star cluster that contains the supermassive black hole Sgr A*. The cluster is embedded in the larger surrounding nuclear stella…
Distribution function-based modelling of discrete kinematic datasets, in application to the Milky Way nuclear star cluster
Eugene Vasiliev, Anja Feldmeier-Krause, Mattia C. Sormani
We present a method for constructing dynamical models of stellar systems described by distribution functions and constrained by discrete-kinematic data. We implement various improv…
oMEGACat. X. Shedding light on the disrupted dwarf galaxy of Omega Centauri
Stefano Souza, Nadine Neumayer, Anil C. Seth +15
Omega Centauri (Cen) is the most massive and chemically complex star cluster in the Milky Way and is widely regarded as the surviving nuclear star cluster of an accreted dwarf…
oMEGACat. IX. Chemical Tagging of Omega Centauri Populations with Machine-Learning-Inferred Abundances from the MUSE Spectrograph
Z. Wang, A. C. Seth, C. Clontz +14
We present chemical abundance measurements for 7,302 red giant branch stars within the half-light radius (~5') of Centauri ( Cen), derived from MUSE spectra using the neural…
Glance: A Comprehensive Framework for Galactic Archaeology
Iris Breda, Glenn van de Ven, Sabine Thater +8
A central topic in extragalactic astronomy is understanding the formation and evolutionary histories of galaxies. These systems often comprise multiple structural components with d…
ReveaLLAGN 1: JWST Emission-Line Spectra Reveal Low-Luminosity AGN with UV-Deficient SEDs and Warm Molecular Gas
Kameron Goold, Anil Seth, Mallory Molina +20
We present near- and mid-infrared spectra of eight Low-Luminosity Active Galactic Nuclei (LLAGN), spanning nearly four orders of magnitude in black hole mass and Eddington ratio, o…
Age and metallicity of the Milky Way's nuclear star cluster studied at 3 pc from Sagittarius A*
E. Gallego-Cano, R. Schödel, T. K. Fritz +5
The Milky Way's nuclear star cluster (NSC) is a unique laboratory to study the formation and evolution of dense stellar systems around a supermassive black hole. Previous work sugg…
Orbital decomposition of the nuclear regions in the early-type galaxy FCC 47: Unveiling the nuclear cluster origin
Julia Lamprecht, Anja Feldmeier-Krause, Mariya Lyubenova +8
Nuclear star clusters (NSCs) are among the densest stellar systems in the Universe and often coexist with supermassive black holes (SMBHs) at galaxy centres. While SMBH formation h…
