    Candidate gravitationally lensed submillimeter galaxies in Herschel-ATLAS associated with WISE elliptical counterparts
    Aims. We present a new and independent methodology for identifying gravitational lens candidates using data from the H-ATLAS and AllWISE surveys. Unlike...

    Candidate high-z protoclusters among the Planck compact sources, as revealed by Herschel-SPIRE
    By determining the nature of all the Planck compact sources within 808.4 deg2 of large Herschel surveys, we have identified 27 candidate protoclusters of dusty...

    Candidate LBV stars in galaxy NGC 7793 found via HST photometry + MUSE spectroscopy
    Only about 19 Galactic and 25 extragalactic bonafide luminous blue variables (LBVs) are known to date. This incomplete census prevents our understanding of this...

    Carbon and oxygen abundance gradients in NGC 300 and M33 from optical recombination lines★
    We present deep spectrophotometry of several H II regions in the nearby low-mass spiral galaxies NGC 300 and M33. The data have been taken with Ultraviolet...

    Carbon and Oxygen Abundances from Recombination Lines in Low Metallicity H II Regions
    We have measured C II and O II recombination lines in several H II regions of low-metallicity dwarf galaxies. These objects show lower C/O ratios than H II...
