SDSS-V Local Volume Mapper (LVM): The Integrated Light and Internal Rotation of Omega Centauri
Maximilian Häberle, Dmitry Bizyaev, Alina Boecker +34
The SDSS-V Local Volume Mapper (LVM) is a wide-field integral field spectroscopic survey of the Southern Milky Way plane, the Magellanic Clouds, and nearby Local Group galaxies. We…
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…
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,…
WIggle Corrector Kit for NIRSpEc Data: WICKED
Antoine Dumont, Nadine Neumayer, Anil C. Seth +8
The point-spread function of the integral-field unit (IFU) mode of the JWST's NIRSpec is heavily under-sampled, creating resampling noise seen as low-frequency sinusoidal-like arti…
A Giant Molecular Cloud Catalog in the Molecular Disk of the Elliptical Galaxy NGC 5128 (Centaurus A)
E. R. Miura, D. Espada, A. Hirota +17
We present the first census of giant molecular clouds (GMCs) complete down to 10 and within the inner 4 kpc of the nearest giant elliptical and powerful radio galaxy,…
Distance to three molecular clouds in the central molecular zone
Francisco Nogueras-Lara, Rainer Schödel, Nadine Neumayer +1
The determination of absolute and relative distances of molecular clouds along the line-of-sight towards the central molecular zone (CMZ) is crucial to infer its orbital structure,…
GALACTICNUCLEUS: A high-angular-resolution JHKs imaging survey of the Galactic centre III. Evidence for wavelength dependence of the extinction curve in the near-infrared
Francisco Nogueras-Lara, Rainer Schödel, Nadine Neumayer +4
The characterisation of the extinction curve in the near infrared (NIR) is fundamental to analyse the structure and stellar population of the Galactic centre (GC), whose analysis i…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. II. Kinematic characterization of the stellar populations
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is in an advanced stage of disruption but still hosts its nuclear star cluster (NSC), M54, at its center. In this paper, we prese…
New constraints on the structure of the nuclear stellar cluster of the Milky Way from star counts and MIR imaging
E. Gallego-Cano, R. Schödel, F. Nogueras-Lara +5
The Milky Way nuclear star cluster (MWNSC) is a crucial laboratory for studying the galactic nuclei of other galaxies, but its properties have not been determined unambiguously unt…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. I. Data and stellar population characterization
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster, M54, which is the only galaxy nucleus that can be resolved into individual stars at o…
Variability of the near-infrared extinction curve towards the Galactic centre
Francisco Nogueras-Lara, Rainer Schödel, Francisco Najarro +4
Due to the extreme extinction towards the Galactic centre ( mag), its stellar population is mainly studied in the near-infrared (NIR) regime. Therefore, a proper ana…
GALACTICNUCLEUS: A high-angular-resolution JHKs imaging survey of the Galactic centre II. First data release of the catalogue and the most detailed CMDs of the GC
Francisco Nogueras-Lara, Rainer Schödel, Aurelia Teresa Gallego-Calvente +7
The high extinction and extreme source crowding of the central regions of the Milky Way are serious obstacles to the study of the structure and stellar population of the Galactic c…
Near-infrared spectroscopic observations of massive young stellar object candidates in the Central Molecular Zone
G. Nandakumar, M. Schultheis, A. Feldmeier-Krause +6
We present a spectroscopic follow-up of photometrically-selected young stellar object (YSO) candidates in the Central Molecular Zone of the Galactic center. Our goal is to quantify…
GALACTICNUCLEUS: A high angular resolution imaging survey of the Galactic Centre. I. Methodology, performance, and near-infrared extinction towards the Galactic Centre
F. Nogueras-Lara, A. T. Gallego-Calvente, H. Dong +8
The Galactic Centre is of fundamental astrophysical interest, but existing near-infrared surveys fall short to cover it adequately. We introduce the GALACTICNUCLEUS survey, a $JHK_…
Triaxial orbit-based modelling of the Milky Way Nuclear Star Cluster
A. Feldmeier-Krause, L. Zhu, N. Neumayer +3
We construct triaxial dynamical models for the Milky Way nuclear star cluster using Schwarzschild's orbit superposition technique. We fit the stellar kinematic maps presented in Fe…
KMOS view of the Galactic Centre I. Young stars are centrally concentrated
A. Feldmeier-Krause, N. Neumayer, R. Schödel +7
The Galactic centre hosts a crowded, dense nuclear star cluster with a half-light radius of 4 pc. Most of the stars in the Galactic centre are cool late-type stars, but there are a…
