    The nucleus of NGC 253 and its massive stellar clusters at parsec scales
    Very Large Telescope adaptive optics images of NGC 253 with resolutions down to 200mas resolve the central 300pc of this galaxy in ~37 infrared (IR) bright...

    The Pressure-confined Wind of the Massive and Compact Super Star Cluster M82-A1
    The observed parameters of the young super star cluster M82-A1 and its associated compact H II region are here shown to indicate a low heating efficiency or...

    The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of He II λ1640 in young star clusters
    We introduce a Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) stellar census of R136a, the central ionizing star cluster of 30 Doradus...

    The relation between the most-massive star and its parental star cluster mass
    We present a thorough literature study of the most-massive star, mmax, in several young star clusters in order to assess whether or not star clusters are...

    The Resolved Stellar Populations in the LEGUS Galaxies1
    The Legacy ExtraGalactic UV Survey (LEGUS) is a multiwavelength Cycle 21 Treasury program on the Hubble Space Telescope. It studied 50 nearby star-forming...

    The S4G Perspective on Circumstellar Dust Extinction of Asymptotic Giant Branch Stars in M100
    We examine the effect of circumstellar dust extinction on the near-IR (NIR) contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters...

    The sensitivity of harassment to orbit: mass loss from early-type dwarfs in galaxy clusters
    We conduct a comprehensive numerical study of the orbital dependence of harassment on early-type dwarfs consisting of 168 different orbits within a realistic...

    The ultraluminous X-ray source NGC 1313 X-2. Its optical counterpart and environment
    NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available...

    The Variation of Integrated Star Initial Mass Functions among Galaxies
    The integrated galaxial initial mass function (IGIMF) is the relevant distribution function containing the information on the distribution of stellar remnants...
