    Supersonic Line Broadening within Young and Massive Super Star Clusters
    The origin of supersonic infrared and radio recombination nebular lines often detected in young and massive superstar clusters is discussed. We suggest that...

    The 100 Myr Star Formation History of NGC 5471 from Cluster and Resolved Stellar Photometry
    We show that star formation in the giant H II region NGC 5471 has been ongoing during the past 100 Myr. Using Hubble Space Telescope/Wide-Field Planetary Camera...

    The ACS Survey of Galactic Globular Clusters: M54 and Young Populations in the Sagittarius Dwarf Spheroidal Galaxy
    As part of the ACS Survey of Galactic Globular Clusters, we present new Hubble Space Telescope photometry of the massive globular cluster M54 (NGC 6715) and the...

    The B-type Binaries Characterisation Programme - II. VFTS 291: a stripped star from a recent mass transfer phase
    Recent studies of massive binaries with putative black hole companions have uncovered a phase of binary evolution that has not been observed before, featuring a...
