A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. III. Discrete multi-component population-dynamical models based on the Jeans equations
Nikolay Kacharov, Mayte Alfaro-Cuello, Nadine Neumayer +12
We present comprehensive multi-component dynamical models of M54 (NGC6715), the nuclear star cluster of the Sagittarius dwarf galaxy (Sgr), which is undergoing a tidal disruption i…
Internal rotation of Milky Way dwarf spheroidal satellites with Early Data Release 3
Alberto Manuel Martínez-García, Andrés del Pino, Antonio Aparicio +2
We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use proper motions (PMs) from the Early Data Release 3 (EDR3) and line-of-sight velocitie…
Hunting for intermediate-mass black holes in globular clusters: an astrometric study of NGC 6441
Maximilian Häberle, Mattia Libralato, Andrea Bellini +6
We present an astrometric study of the proper motions (PMs) in the core of the globular cluster NGC 6441. The core of this cluster has a high density and observations with current…
Disentangling the formation history of galaxies via population-orbit superposition: method validation
Ling Zhu, Glenn van de Ven, Ryan Leaman +9
We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and metallicity. The mode…
The peculiar kinematics of the multiple populations in the globular cluster Messier 80 (NGC 6093)
Sebastian Kamann, Emanuele Dalessandro, Nate Bastian +10
We combine MUSE spectroscopy and Hubble Space Telescope ultraviolet (UV) photometry to perform a study of the chemistry and dynamics of the Galactic globular cluster Messier 80 (M8…
Imprints of Evolution on the Internal Kinematics of Globular Clusters
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +2
Globular clusters are collisional systems, meaning that the stars inside them interact on timescales much shorter than the age of the Universe. These frequent interactions transfer…
