    Nuclear Starburst Hydrodynamics
    We present calculations that account for the infall of matter onto the heart of a starburst, a condition thought indispensable for causing the large...

    Nucleosynthesis and the Inhomogeneous Chemical Evolution of the Carina Dwarf Galaxy
    The detailed abundances of 23 chemical elements in nine bright red giant branch stars in the Carina dwarf spheroidal galaxy are presented based on high...

    Numerical simulations of dark matter haloes produce polytropic central cores when reaching thermodynamic equilibrium
    Self-gravitating astronomical objects often show a central plateau in the density profile (core) whose physical origin is hotly debated. Cores are theoretically...

    OASIS high-resolution integral field spectroscopy of the SAURON ellipticals and lenticulars
    We present a summary of high-spatial resolution follow-up observations of the elliptical (E) and lenticular (S0) galaxies in the SAURON survey using the OASIS...

    OB associations in IC 1613 (Garcia+, 2009)
    From observations taken with the Wide Field Camera (WFC) at the Isaac Newton Telescope (INT), we have built an astrometric and photometric catalogue of stars in...

    Obscuration beyond the nucleus: infrared quasars can be buried in extreme compact starbursts
    In the standard quasar model, the accretion disc obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar...

    Obscured active galactic nuclei from the ELAIS Deep X-ray Survey
    The sources discovered in deep hard X-ray surveys with 2-8 keV fluxes of S2-8˜ 10-14 erg cm-2 s-1 make up the bulk of the X-ray background at these energies...
