A cautionary lesson from Gaia systematics: the mono-metallic globular cluster NGC 5904
Paolo Bianchini, Alessandra Mastrobuono-Battisti
The study of the chemistry of the stellar populations in Globular Clusters (GCs) is a fundamental task to unveil their formation in the high-redshift universe and to reconstruct th…
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…
Using Binaries in Globular Clusters to Catch Sight of Intermediate-Mass Black Holes
Francisco I. Aros, Anna C. Sippel, Alessandra Mastrobuono-Battisti +3
The dynamical evolution of globular clusters (GCs) is tied to their binary population, as binaries segregate to the cluster centre, leading to an increased binary fraction in the c…
Predicting Images for the Dynamics Of stellar Clusters (π-DOC): a deep learning framework to predict mass, distance and age of globular clusters
Jonathan Chardin, Paolo Bianchini
Dynamical mass estimates of simple systems such globular clusters (GCs) still suffer from up to a factor of 2 uncertainty. This is primarily due to the oversimplifications of stand…
Charting the Galactic acceleration field I. A search for stellar streams with Gaia DR2 and EDR3 with follow-up from ESPaDOnS and UVES
Rodrigo Ibata, Khyati Malhan, Nicolas Martin +10
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We also report the spect…
Dynamical modelling of globular clusters: challenges for the robust determination of IMBH candidates
Francisco I. Aros, Anna C. Sippel, Alessandra Mastrobuono-Battisti +3
The presence or absence of intermediate-mass black holes (IMBHs) at the centre of Milky Way globular clusters (GCs) is still an open question. This is either due to observational r…
