    On the origin of the compact H ii regions around massive stellar clusters
    The existence of compact H ii regions around massive stellar clusters with ages exceeding several Myr challenges our understanding of the physical processes...

    On the Origin of the HII Regions Associated with Massive and Compact Superstar Clusters
    This contribution to the IV Korea-Mexico meeting deals with the hydrodynamics of the matter reinserted within super star clusters (SSCs) by both stellar winds...

    On the Star Formation Efficiencies and Evolution of Multiple Stellar Generations in Globular Clusters
    By adopting empirical estimates of the helium enhancement (ΔY) between consecutive stellar generations for a sample of Galactic globular clusters (GGCs), we...

    Open Cluster Chemical Homogeneity throughout the Milky Way
    The chemical homogeneity of surviving stellar clusters contains important clues about interstellar medium (ISM) mixing efficiency, star formation, and the...

    Optical Properties of the Ultraluminous X-Ray Source Holmberg IX X-1 and Its Stellar Environment
    Holmberg IX X-1 is an archetypal ultraluminous X-ray source (ULX). Here we study the properties of the optical counterpart and of its stellar environment using...

    PHANGS-HST Catalogs for ∼100,000 Star Clusters and Compact Associations in 38 Galaxies. I. Observed Properties
    We present the largest catalog to date of star clusters and compact associations in nearby galaxies. We have performed a V-band-selected census of clusters...

    Photoionization Models of NGC 2363 and Their Implications for the Ionizing Star Cluster
    Using the photoionization code CLOUDY, we compute photoionization models for the giant extragalactic H II region NGC 2363 and compare them with optical...

    Photometric Properties of the M33 Star Cluster System
    We present a catalog of 2990 extended sources in a 1° × 1° area centered on M33 using the MegaCam camera on the 3.6 m Canada-France-Hawaii Telescope. The...

    Physical limits to the validity of synthesis models. The Lowest Luminosity Limit
    In this paper we establish a necessary condition for the application of stellar population synthesis models to observed star clusters. Such a condition is...
