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…

The Hubble Missing Globular Cluster Survey. III. Astro-photometric catalogs, artificial-star tests, and improved absolute proper motions

M. Libralato, A. Bellini, D. Massari +17

The Hubble Missing Globular Cluster Survey (MGCS) has taken one of the last opportunities to complete the census of Galactic globular clusters (GCs) started by past Hubble Space Te…

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…

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs

Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16

Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) -- III. Age and metallicity distribution of Gaia-Sausage-Enceladus stars near the Sun

Yllari K. González-Koda, Tomás Ruiz-Lara, Carme Gallart +14

Context. Gaia-Sausage-Enceladus is considered the last major merger that contributed to the formation of the Milky Way. Its remnants dominate the nearby accreted stellar halo of th…

Unevolved Li-rich stars at low metallicity: a possible formation pathway through novae

Tadafumi Matsuno, Alex Kemp, Ataru Tanikawa +7

A small fraction of low-mass stars have been found to have anomalously high Li abundances. Although it has been suggested that mixing during the red giant branch phase can lead to…

Chemical characterisation of small substructures in the local stellar halo

Emma Dodd, Tadafumi Matsuno, Amina Helmi +5

The local stellar halo of the Milky Way is known to contain the debris from accreted dwarf galaxies and globular clusters, in the form of stellar streams and over-densities in the…

Characterisation of local halo building blocks: Thamnos and Sequoia

Emma Dodd, Tomás Ruiz-Lara, Amina Helmi +5

A crucial aspect of galaxy evolution is the pace at which galaxies build up their mass. We investigate this hierarchical assembly by uncovering and timing accretion events experien…
