    Looking into the faintEst WIth MUSE (LEWIS): Exploring the nature of ultra-diffuse galaxies in the Hydra-I cluster: IV. A study of the globular cluster population in four ultra-diffuse galaxies
    Context. As some of the oldest stellar systems in the Universe, globular clusters (GCs) are key fossil tracers of galaxy formation and interaction histories...

    Low-density star cluster formation: discovery of a young faint fuzzy on the outskirts of the low-mass spiral galaxy NGC 247
    The classical globular clusters found in all galaxy types have half-light radii of r h ~ 2-4 pc, which have been tied to formation in the dense cores of giant...

    Low-metallicity globular clusters in the low-mass isolated spiral galaxy NGC 2403
    The globular cluster (GC) systems of low-mass late-type galaxies, such as NGC 2403, have been poorly studied to date. As a low mass galaxy (M * = 7 × 10 9 M ⊙)...

    Mapping the core of the Tarantula Nebula with VLT-MUSE. II. The spectroscopic Hertzsprung-Russell diagram of OB stars in NGC 2070
    We present the spectroscopic analysis of 333 OB-type stars extracted from VLT-MUSE observations of the central 30 × 30 pc of NGC 2070 in the Tarantula Nebula on...

    Masgomas-1: Discovery of a young, obscured and massive stellar cluster
    I am going to present the new massive and obscured cluster Masgomas-1. This cluster, discovered by our group formed by astronomers from the IAC and CEFCA, is...

    Massive young clusters in the Milky Way and the Scutum Complex
    The last decade has brought the discovery of a large number of massive (M > 10000 M?) young open clusters in the Milky Way, which had previously not been...

    Missing dust of super-early galaxies: Supernova blowout and gas─dust venting in blue monsters
    Context. A subset of very young super-early galaxies at z ≳ 10, often called blue monsters, shows extremely blue UV continua and faint far-IR emission. This...

    MIUSCAT: extended MILES spectral coverage - II. Constraints from optical photometry
    In this work, we show a comprehensive comparison of our new stellar population synthesis (SPS) MIUSCAT models with photometric data of globular clusters (GCs)...

    Modeling the ionizing spectra of H II regions: individual stars versus stellar ensembles
    Aims: We study how IMF sampling affects the ionizing flux and emission line spectra of low mass stellar clusters. Methods: We performed 2 × 106 Monte Carlo...
