X-shooter spectroscopy of giant stars in the nuclear star cluster
L. Origlia, C. Fanelli, A. Mucciarelli +5
Near-IR spectra of a homogeneous sample of 15 red giants in the Galactic nuclear star cluster, within 1.5 pc of SgrA*, have been acquired with X-shooter at the Very Large Telescope…
PySME v1.0: improved modelling of stellar spectra for survey-scale applications
Mingjie Jian, Nikolai Piskunov, Jeff Valenti +4
Stellar abundance analysis relies on flexible, high-performance spectral synthesis. To meet these needs, we present PySME v1.0, an updated Python implementation of Spectroscopy Mad…
The LEGARE Project. I. Chemical evolution model of the Nuclear Stellar Disc in a Bayesian framework
E. Spitoni, M. Schultheis, F. Matteucci +5
The Nuclear Stellar Disc (NSD) of the Milky Way is a dense, rotating stellar system in the central 200 pc. The NSD is thought to be primarily fuelled by bar-driven gas inflows from…
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…
The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
Supergiant GCIRS 22 in the Milky Way Nuclear Star Cluster: Revised alpha abundances
B. Thorsbro, S. Khalidy, R. M. Rich +7
Context: The chemical abundances of alpha-elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way…
