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. II. Survey membership tools and kinematic analysis of NGC 6749
L. Rosignoli, M. Libralato, R. Pascale +15
The Hubble Missing Globular Cluster Survey has secured high quality astro photometric data in two bands for 34 clusters never observed with HST. When combined with Gaia positional…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA) IV. Chrono-dynamics of seven old star clusters in the Large Magellanic Cloud and the peculiar origin of NGC 1841
F. Niederhofer, D. Massari, F. Aguado-Agelet +15
In this study, we report conclusive evidence for an ancient star cluster that has been accreted by the Large Magellanic Cloud (LMC). By leveraging observations from the Hubble Spac…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA). III. NGC 288 as the first Splashed globular cluster
E. Ceccarelli, D. Massari, F. Aguado-Agelet +6
The system of globular clusters (GCs) in the Milky Way (MW) comprises a mixture of both in situ and accreted clusters. Tracing the origin of GCs provides invaluable insights into t…
The Missing Globular Cluster Survey. I. Survey overview and the first precise age estimate for ESO452-11 and 2MASS-GC01
D. Massari, M. Bellazzini, M. Libralato +17
We present the Missing Globular Cluster Survey (MGCS), a Treasury Program dedicated to the observation of all kinematically confirmed Milky Wa…
Differential reddening in 48 globular clusters: An end to the quest for the intracluster medium
E. Pancino, A. Zocchi, M. Rainer +9
For decades, it has been theorized that a tenuous but detectable intracluster medium should be present in globular clusters, which is continuously replenished by the gas and dust e…
Chronology of our Galaxy from Gaia Colour-Magnitude Diagram-fitting (ChronoGal). I. The formation and evolution of the thin disk from the Gaia Catalogue of Nearby Stars
C. Gallart, F. Surot, S. Cassisi +15
The current major challenge to reconstruct the chronology of the Milky Way (MW) is the difficulty to derive precise stellar ages. CMD-fitting offers an alternative to individual ag…
First spectroscopic investigation of Anomalous Cepheid variables
V. Ripepi, G. Catanzaro, E. Trentin +12
Anomalous Cepheids (ACEPs) are intermediate mass metal-poor pulsators mostly discovered in dwarf galaxies of the Local Group. However, recent Galactic surveys, including the Gaia D…
The synchronised dance of the Magellanic Clouds' star formation history
P. Massana, T. Ruiz-Lara, N. E. D. Noël +17
We use the SMASH survey to obtain unprecedented deep photometry reaching down to the oldest main sequence turn-offs in the colour-magnitude diagrams (CMDs) of the Small Magellanic…
Dissecting the stellar content of Leo I: a dwarf irregular caught in transition
T. Ruiz-Lara, C. Gallart, M. Monelli +7
Leo I is considered one of the youngest dwarf spheroidals (dSph) in the Local Group. Its isolation, extended star formation history (SFH), and recent perigalacticon passage (~1 Gyr…
The HST/ACS star formation history of the Tucana dwarf spheroidal galaxy: clues from the horizontal branch
A. Savino, E. Tolstoy, M. Salaris +2
We report a new star formation history for the Tucana dwarf spheroidal galaxy, obtained from a new look at a deep HST/ACS colour-magnitude diagram. We combined information from the…
On the nature of a shell of young stars in the outskirts of the Small Magellanic Cloud
David Martinez-Delgado, A. Katherina Vivas, Eva K. Grebel +35
Understanding the evolutionary history of the Magellanic Clouds requires an in-depth exploration and characterization of the stellar content in their outer regions, which ultimatel…
3D kinematics through the X-shaped Milky Way bulge
S. Vásquez, M. Zoccali, V. Hill +10
It has recently been discovered that the Galactic bulge is X-shaped, with the two southern arms of the X both crossing the lines of sight at l=0 and |b|>4, hence producing a double…
