    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 (sub-SMC) massive stars
    The double distance and metallicity frontier marked by the SMC has been finally broken with the aid of powerful multi-object spectrographs installed at 8-10m...
