    High velocity clouds around nearby galaxies from THINGS
    As a sub-set of activities within the THINGS (The HI Nearby Galaxy Survey) collaboration we have used the HI maps of the complete set of galaxies observed in...
  • Publication
    High z Radio-Loud and Radio-Quiet QSO Environments
    We propose a systematic study of the environments of a representative sample of Radio Loud Quasars (RLQ) and Radio Quiet Quasars (RQQ) in two different redshift...

    High-Ionization Clouds in the Circumnuclear Region of M31
    We present two-dimensional spectroscopy of the 125×125 pc2 circumnuclear region of M31, obtained using two optical fiber systems, INTEGRAL and 2D-FIS, installed...

    High-redshift BL Lac Objects: Spectroscopy of Candidates
    We report on 16 BL Lacertae objects that were proposed to be at z > 1. We present spectroscopic observations secured at the 10.4 m GTC that allowed us to assess...

    High-redshift lensed galaxies
    We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z˜6 11.

    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...
  • Publication
    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...
