Observational Properties of Field UDGs: Colours and Number Densities
Daniel J. Prole, Remco F. J. van der Burg, Michael Hilker +1
While much of the focus around Ultra-Diffuse Galaxies (UDGs) has been given to those in galaxy groups and clusters, relatively little is known about them in less-dense environments…
Astroinformatics based search for globular clusters in the Fornax Deep Survey
Giuseppe Angora, Massimo Brescia, Stefano Cavuoti +15
In the last years, Astroinformatics has become a well defined paradigm for many fields of Astronomy. In this work we demonstrate the potential of a multidisciplinary approach to id…
Early formation and recent starburst activity in the nuclear disc of the Milky Way
F. Nogueras-Lara, R. Schödel, A. T. Gallego-Calvente +10
The nuclear disc is a dense stellar structure at the centre of the Milky Way, with a radius of 150 pc. It has been a place of intense star formation in the past several tens…
Multiple Populations in Integrated Light Spectroscopy of Intermediate Age Clusters
Nate Bastian, Christopher Usher, Sebastian Kamann +9
The presence of star-to-star light-element abundance variations (a.k.a. multiple populations, MPs) appears to be ubiquitous within old and massive clusters in the Milky Way and all…
Kinematics of Multiple Stellar Populations in Globular Clusters with Gaia
Giacomo Cordoni, Antonino P. Milone, Alessandra Mastrobuono-Battisti +3
The internal dynamics of multiple stellar populations in Globular Clusters (GCs) provides unique constraints on the physical processes responsible for their formation. Specifically…
Galactic globular clusters: a new catalog of masses, structural parameters, velocity dispersion profiles, proper motions and space orbits
Michael Hilker, Holger Baumgardt, Antonio Sollima +1
We collected radial velocities of more than 50.000 individual stars in 156 Galactic globular clusters (GGC) and matched them with HST photometry and Gaia DR2 proper motions. This a…
