Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Mapping formation pathways of nuclear star clusters across galaxies
Francesca Pinna, Isabel Pérez, Anna Ferré-Mateu +21
Nuclear star clusters (NSCs) are dense, compact stellar systems only a few parsecs across, located at galaxy centers. Their small sizes make them difficult to resolve spatially. NS…
Chemical analysis of the Milky Way's Nuclear Star Cluster: Evidence for a metallicity gradient
M. Schultheis, L. Serrano, B. Thorsbro +5
The Milky Way nuclear star cluster (MWNSC) is located together with its surrounding nuclear stellar disc (MWNSD) in the Galactic centre and they dominate the gravitational potentia…
oMEGACat. VIII. A Subpopulation Census of ω Centauri
C. Clontz, A. C. Seth, Z. Wang +8
An understanding of the assembly history of the complex star cluster Omega Centauri has long been sought after, with many studies separating the stars on the color-magnitude diagra…
oMEGACat. VII. Tracing Interstellar and Intracluster Medium of Centauri using Sodium Absorptions
Z. Wang, A. C. Seth, M. Latour +14
We investigate the foreground interstellar medium along the line of sight and intracluster medium of Centauri ( Cen) by measuring the equivalent width of Na I D absorptions…
A Comparison of Full Spectral Fitting Codes for Measuring the Stellar Initial Mass Function and Other Stellar Population Properties in Elliptical Galaxies
Ilaria Lonoce, Anja Feldmeier-Krause, Alexandra Masegian +1
We present a comparative test of four widely used full spectral fitting codes, with the aim of answering the question: how robust is the retrieval of the stellar initial mass funct…
Dynamical mass distribution and velocity structure of the Galactic centre
A. Feldmeier-Krause, T. Veršič, G. van de Ven +2
The inner ~200 pc region of the Milky Way contains a nuclear stellar disc and a nuclear star cluster that are embedded in the larger Galactic bar. These stellar systems overlap spa…
oMEGACat. VI. Analysis of the overall kinematics of Omega Centauri in 3D: velocity dispersion, kinematic distance, anisotropy, and energy equipartition
Maximilian Häberle, Nadine Neumayer, Callie Clontz +15
Omega Centauri ( Cen) is the Milky Way's most massive globular cluster and is likely the stripped nucleus of an accreted dwarf galaxy. In this paper, we analyze Cen's kinema…
A spectroscopic map of the Galactic centre -- Observations and resolved stars
A. Feldmeier-Krause, N. Neumayer, A. Seth +10
The Galactic Centre region contains a dense accumulation of stars, which can be separated into two components: A flattened and dense nuclear star cluster (NSC), and a surrounding,…
