The evolution of high-z proto-star clusters into local globular clusters

A. Della Croce, E. Vesperini, R. Pascale +4

The James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z>0.5). Their properties suggest that…

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…

Euclid: Early Release Observations -- The extended stellar component of the IC10 dwarf galaxy

F. Annibali, A. M. N. Ferguson, P. M. Sanchez-Alarcon +175

We present a detailed analysis of the old, extended stellar component of the Local Group dwarf galaxy IC 10 using deep resolved-star photometry in the VIS and NISP bands of the Euc…

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…

RGB Tip distance to the faint gas-rich dwarf KK 153

M. Bellazzini, G. Beccari, R. Pascale +4

KK 153 is a star-forming dwarf galaxy that has been recently proposed as a new member of the sparsely populated class of gas-rich ultra faint dwarfs, lying in the outskirts of the…
