    Determination of O and Fe abundances in the metal poor stars
    The abundances of oxygen and iron in metal-poor stars have been determined through non-LTE radiative transfer simulations in three-dimensional (3D)...

    Determination of oxygen abundances in stars with planets
    A study comparing the oxygen abundance of stars with planets to stars without planets has been completed. By looking at various indicators of the O abundance...

    Determination of the range of masses for the compact object in binary r-X 2S 0921-630
    The range of masses for the compact object in binary r-X 2S 0921-630 has been determined (between 2.0-4.3 solar masses), consistent with a massive neutron star...

    Discovered one of the brightest distant galaxies so far known
    In the phenomenon of gravitational lensing, predicted by Einstein's General Theory of Relativity, the mass of a galaxy acts on the light of a more distant...

    Discovery of a massive supercluster system at z=0.47
    Superclusters are the largest over-dense, relatively isolated systems in the cosmic web. They provide us invaluable information about the large-scale structure...

    Discovery of a massive black hole companion to a B-type star from radial velocity measurements
    All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems...
