    The young stellar population of IC 1613. II. Physical properties of OB associations
    Context. To understand the structure and evolution of massive stars, systematic surveys of the Local Group galaxies have been undertaken, to find these objects...

    Thinking about stellar populations modeling
    The basis of stellar population modeling was established around 40 years ago somehow optimized to the technical facilities and observational data available at...

    Three supernova shells around a young M33 star cluster
    Using a specialized technique sensitive to the presence of expanding ionized gas, we have detected a set of three concentric expanding shells in an H II region...

    Top-heavy integrated galactic stellar initial mass functions in starbursts
    Star formation rates (SFRs) larger than 1000 M&sun; yr-1 are observed in extreme starbursts. This leads to the formation of star clusters with masses >106 M&sun...

    Two newly identified, relatively old star clusters in the Small Magellanic Cloud
    We present the results on the age and metallicity estimates of the Small Magellanic Cloud (SMC) clusters L110, L112 and L113 obtained from CCD Washington CT1...

    UBRI photometry of globular clusters in the Leo group galaxy NGC 3379
    We present wide-area UBRI photometry for globular clusters around the Leo group galaxy NGC 3379. Globular cluster candidates are selected from their B-band...

    Ultra diffuse galaxies in the Hydra I cluster from the LEWISProject: Phase-Space distribution and globular cluster richness
    Although ultra diffuse galaxies (UDGs) are found in large numbers in clusters of galaxies, the role of the cluster environment in shaping their low surface...

    Uncertainty-aware blob detection with an application to integrated-light stellar population recoveries
    Context. Blob detection is a common problem in astronomy. One example is in stellar population modelling, where the distribution of stellar ages and...

    Undressing M87 by Exposing its Most Private Globulars
    We present a multiwavelength photometric analysis of the innermost (3×3 kpc2) Globular Clusters (GCs) of M87. Their Spectral Energy Distributions (SEDs) were...
