The Milky Way and the Local Group (MWLG)
  • Publication
    Chlorine abundances in star-forming regions of the local Universe
    Aims. We aim to study the behaviour of Cl abundance and its ratios with respect to O, S, and Ar abundances in a sample of more than 200 spectra of Galactic and...
  • Publication
    Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal). I. The formation and evolution of the thin disc from the Gaia Catalogue of Nearby Stars
    Context. The study of the Milky Way is living a golden era thanks to the enormous high-quality datasets delivered by Gaia, and space asteroseismic and ground...
  • Publication
    Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): III. Age and metallicity distribution of Gaia-Sausage-Enceladus stars near the Sun
    Context. Gaia-Sausage-Enceladus is considered the last major merger that contributed to the formation of the Milky Way. Its remnants dominate the nearby...
  • Publication
    Circumstellar effects on the Rb abundances in O-rich AGB stars
    For the first time we explore the circumstellar effects on the Rb (and Zr) abundance determination in O-rich asymptotic giant branch (AGB) stars by considering...
  • Publication
    Clear Evidence for the Presence of Second-generation Asymptotic Giant Branch Stars in Metal-poor Galactic Globular Clusters
    Galactic globular clusters (GCs) are known to host multiple stellar populations: a first generation (FG) with a chemical pattern typical of halo field stars and...
  • Publication
    Close Binary Companions to APOGEE DR16 Stars: 20,000 Binary-star Systems Across the Color-Magnitude Diagram
    Many problems in contemporary astrophysics—from understanding the formation of black holes to untangling the chemical evolution of galaxies—rely on knowledge...
  • Publication
    Cluster Ages to Reconstruct the Milky Way Assembly (CARMA). I. The final word on the origin of NGC 6388 and NGC 6441
    We present CARMA, the Cluster Ages to Reconstruct the Milky Way Assembly project, the aim of which is to determine precise and accurate age measurements for the...
  • Publication
    Cluster Ages to Reconstruct the Milky Way Assembly (CARMA): II. The age-metallicity relation of Gaia─Sausage─Enceladus globular clusters
    We present the age determination of 13 globular clusters that are dynamically associated with the Gaia-Sausage-Enceladus (GSE) merger event, as part of the...
  • Publication
    Cluster membership for the long-period Cepheid calibrator SV Vul
    Classical Cepheids represent the first step of the distance scale ladder. Claims of tension between the locally calculated Hubble constant and the values...
