    High-Resolution H I Observations of the Galaxy NGC 404: A Dwarf S0 with Abundant Interstellar Gas
    As part of a detailed study of the gas content in a sample of early-type galaxies, we present 21 cm H I line maps of the S0 galaxy NGC 404 at a spatial...

    High-Resolution Spectroscopy of H II Galaxies: Structure and Supersonic Line Widths
    We present high-resolution echelle spectroscopy of a sample of H II galaxies. In all galaxies we identify different Hα-emitting knots along the slit crossing...

    High-resolution spectroscopy of the Seyfert galaxy MRK 595 in the direction of the Cohen HI high-velocity stream
    We have obtained a spectrum of the Na D lines of the Seyfert galaxy Mrk 595 with a signal-to-noise ratio (S/N) of about 30. The importance of this sightline is...

    High-spatial resolution SED of NGC 1068 from near-IR to radio. Disentangling the thermal and non-thermal contributions
    We investigate the idea that a sizable fraction of the interferometrically unresolved infrared emission of the nucleus of NGC 1068 might originate from...

    High-velocity clouds as dark matter in the Local Group
    The High-Velocity Clouds (HVCs) observed in the Galactic neighbourhood, have been proposed to be remnants of the formation of the galaxies in the Local Group...

    High-Velocity Gas in the Luminous H II Regions of NGC 1530
    We are carrying out a systematic study of the ensuremath {{H}alpha } emission line profiles from the H II regions in NGC 1530 (Knapen et al. 2001) based on a...

    High-z Galaxies Through Gravitational Lensing
    Gravity is the key engine for the evolution of the universe and the formation of its main structures: galaxies, clusters of galaxies and filaments. Gravity is...

    High-z Sudoku: a diagnostic tool for identifying robust (sub)mm redshifts
    We present methods to (i) graphically identify robust redshifts using emission lines in the (sub)mm regime, (ii) evaluate the capabilities of different (sub)mm...
