    The shell elliptical galaxy NGC 2865: evolutionary population synthesis of a kinematically distinct core
    We report on the discovery of a rapidly corotating stellar and gas component in the nucleus of the shell elliptical NGC 2865. The stellar component extends ~ 0...

    The shortest period detached binary white dwarf system
    We identify SDSS J010657.39-100003.3 (hereafter J0106-1000) as the shortest period detached binary white dwarf (WD) system currently known. We targeted J0106...

    The shortest period detached white dwarf + main-sequence binary
    We present high-speed ULTRACAM and SOFI photometry and X-shooter spectroscopy of the recently discovered 94-min orbital period eclipsing white dwarf/main...
  • Publication
    The sigma Orionis substellar population. VLT/FORS spectroscopy and 2MASS photometry
    VLT/FORS spectroscopy and 2MASS near-infrared photometry, together with previously known data, have been used to establish the membership and the properties of...

    The signal of decaying dark matter with hydrodynamical simulations
    Dark matter particles may decay, emitting photons. Drawing on the EAGLE family of hydrodynamical simulations of galaxy formation - including the APOSTLE and C...

    The signature of chromospheric heating in Ca II H spectra
    Context: The heating process that balances the solar chromospheric energy losses has not yet been determined. Conflicting views exist on the source of the...

    The signature of high-velocity gas in the spectra of NGC 4151
    The multiwavelength emission spectrum and associated velocity field of the Seyfert prototype NGC 4151 is modeled. Since the thirties NGC 4151 has been the...

    The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge
    We compare abundance ratio trends in a sample of ∼11,000 Milky Way bulge stars (R GC < 3 kpc) from the Apache Point Observatory Galactic Evolution Experiment...
