The oldest, most metal-poor stars in the Galactic halo and satellite dwarf galaxies present an
opportunity to explore the chemical and physical conditions of the earliest star-forming …

Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters
of stars, they exhibit signs of some chemical evolution. At least for this reason, they are …

Context. The assembly history experienced by the Milky Way is currently being unveiled
thanks to the data provided by the Gaia mission. It is likely that the globular cluster system of …

We use the age–metallicity distribution of 96 Galactic globular clusters (GCs) to infer the
formation and assembly history of the Milky Way (MW), culminating in the reconstruction of …

We use high-precision photometry of red-giant-branch (RGB) stars in 57 Galactic globular
clusters (GCs), mostly from the 'Hubble Space Telescope (HST) UV Legacy Survey of …

Globular clusters (GCs) formed when the Milky Way experienced a phase of rapid assembly.
We use the wealth of information contained in the Galactic GC population to quantify the …

In this paper we describe a new UV-initiative Hubble Space Telescope project (GO-13297)
that will complement the existing F606W and F814W database of the Advanced Camera for …

Abstract We introduce the MOdelling Star cluster population Assembly In Cosmological
Simulations within EAGLE (E-MOSAICS) project. E-MOSAICS incorporates models …

Ages have been derived for 55 globular clusters (GCs) for which Hubble Space Telescope
Advanced Camera for Surveys photometry is publicly available. For most of them, the …

We present synthetic spectral energy distributions (SEDs) for single-age, single-metallicity
stellar populations (SSPs) covering the full optical spectral range at moderately high …
