    Globular clusters systems and their host dark matter halos
    In the Λ-CDM galaxy formation paradigm, the star formation history of a galaxy is coupled to the total mass of its dark matter halo through processes like...

    GTC spectroscopic study of stellar clusters in M81
    The nearby spiral galaxy M81 contains a population of 3 kinds of stellar clusters - super star clusters, globular clusters and fuzzy clusters. Over the past few...

    H α morphologies of star clusters: a LEGUS study of H II region evolution time-scales and stochasticity in low-mass clusters
    The morphology of H II regions around young star clusters provides insight into the time-scales and physical processes that clear a cluster's natal gas. We...

    Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351
    We use 0.1″ observations from the Atacama Large Millimeter Array (ALMA), Hubble Space Telescope (HST), and JWST to study young massive clusters (YMCs) in their...

    High resolution images of the embedded cluster associated with GM24.
    High resolution visual and IR images of the embedded young cluster associated with the molecular cloud and "blister" H II region GM24 are presented. The cluster...

    High resolution IR observations of the starburst ring in NGC 7552. One ring to rule them all?
    Aims: Approximately 20% of all spiral galaxies display starburst activity in nuclear rings of a few hundred parsecs in diameter. It is our main aim to...

    Hubble Space Telescope ACS Wide-Field Photometry of the Sombrero Galaxy Globular Cluster System
    A detailed imaging analysis of the globular cluster (GC) system of the Sombrero galaxy (NGC 4594) has been accomplished using a six-image mosaic from the Hubble...

    Hubble Space Telescope Observations of Accretion-Induced Star Formation in the Tadpole Galaxy Kiso 5639
    The tadpole galaxy Kiso 5639 has a slowly rotating disk with a drop in metallicity at its star-forming head, suggesting that star formation was triggered by the...

    Hubble Space Telescope-NICMOS Observations of M31'S Metal-Rich Globular Clusters and Their Surrounding Fields. I. Techniques
    Astronomers are always anxious to push their observations to the limit-basing results on objects at the detection threshold, spectral features barely stronger...
