    The History of a Quiet-Sun Magnetic Element Revealed by IMaX/SUNRISE
    Isolated flux tubes are considered to be fundamental magnetic building blocks of the solar photosphere. Their formation is usually attributed to the...

    The Hobby-Eberly Telescope Chemical Abundances of Stars in the Halo (CASH) Project. I. The Lithium-, s-, and r-enhanced Metal-poor Giant HKII 17435-00532
    We present the first detailed abundance analysis of the metal-poor giant HKII 17435-00532. This star was observed as part of the University of Texas long-term...
  • Publication
    The homogeneity of chemical abundances in H II regions of the Magellanic Clouds
    We use very deep spectra obtained with the Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope to derive physical conditions and chemical...
  • Publication
    The Horizontal Magnetic Flux of the Quiet-Sun Internetwork as Observed with the Hinode Spectro-Polarimeter
    Observations of very quiet Sun using the Solar Optical Telescope/Spectro-Polarimeter (SOT/SP) aboard the Hinode spacecraft reveal that the quiet internetwork...

    The host galaxies of BL Lac objects in the near-infrared
    We present the results of near-infrared H band (1.65 μm) imaging of 11 BL Lac objects with redshifts ranging from z = 0.05 to 0.9. We are able to clearly detect...

    The Host Galaxies of Radio-loud Active Galactic Nuclei: The Black Hole-Galaxy Connection
    We have studied the host galaxies of a sample of radio-loud active galactic nuclei (AGNs) spanning more than 4 decades in the energy output of the nucleus. The...

    The Host Galaxy of the Lensed Quasar Q0957+561
    Infrared images of the Q0957+561 gravitational lens obtained with the Hubble Space Telescope show two large (~5") lensed images of the zs=1.41 quasar host...

    The host galaxy of the γ-ray-emitting narrow-line Seyfert 1 galaxy PKS 1502+036
    The detection of γ-ray emission from narrow-line Seyfert 1 galaxies (NLSy1) has challenged the idea that large black hole (BH) masses (≥108 M⊙) are needed to...

    The host in blue compact galaxies.. Structural properties and scaling relations
    Aims: We characterise the underlying stellar host in a sample of 20 blue compact galaxies (BCGs), by fitting their two-dimensional light distributions. Their...
