Low-resolution spectroscopic characterisation of five poorly known Galactic stellar clusters
E. Ceccarelli, M. Bellazzini, D. Massari +4
Stellar clusters preserve crucial information on the formation and evolutionary processes that shaped the Milky Way (MW) as we see it today. However, several MW clusters still lack…
The Hubble Missing Globular Clusters Survey IV. Ultra-faint compact satellites of the Milky Way. The case of Koposov 2
M. Bellazzini, R. Pascale, E. Dodd +16
In the last decades a number of extremely faint and compact Galactic satellites (Ultra Faint Compact Satellites; UFCS) have been discovered by large panoramic surveys. Their nature…
Probing the Milky Way Halo with RR Lyrae Stars from Gaia Data Release 3
T. Muraveva, L. Monti, D. Massari +5
The Milky Way (MW) stellar halo, containing debris from past accretion events, serves as a fossil record of hierarchical mass assembly. Due to their distinct properties, RR Lyrae s…
Globular clusters in \textsc{OrbIT}: complete dynamical characterisation of the globular cluster population of the Milky Way through updated orbital reconstruction
Michele De Leo, Manuela Zoccali, Julio Olivares-Carvajal +3
In hierarchical structure formation, the content of a galaxy is determined both by its in-situ processes and by material added via accretions. Globular clusters in particular repre…
Dynamical mirages: how bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces
Michele De Leo, Davide Massari, Michele Bellazzini +3
The complex task of unraveling the assembly history of the Milky Way is in constant evolution with new substructures identified continuously. To properly validate and characterise…
