    New brown dwarfs in Upper Sco using UKIDSS Galactic Cluster Survey science verification data
    We present first results from a deep (J = 18.7), wide-field (6.5deg2) infrared (ZY JHK) survey in the Upper Sco association conducted within the science...

    New faint optical spectrophotometric standards: hot white dwarfs from the Sloan Digital Sky Survey
    The spectral energy distributions for pure-hydrogen (DA) hot white dwarfs can be accurately predicted by model atmospheres. This makes it possible to define...
