    Unveiling the Active Nucleus of Centaurus A
    We report new Hubble Space Telescope WFPC2 and NICMOS observations of the center of the nearest radio galaxy Centaurus A (NGC 5128) and discuss their...

    Unveiling the Central Parsec Region of an Active Galactic Nucleus: The Circinus Nucleus in the Near-Infrared with the Very Large Telescope
    VLT J- to M'-band adaptive optics observations of the Circinus galaxy on parsec scales resolve a central bright Ks-band source with a FWHM size of 1.9+/-0.6 pc...

    Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations
    Context. Asymmetries in atomic hydrogen (HI) in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework...

    Unveiling the monster heart: unbeamed properties of blazar 4C 71.07
    4C 71.07 is a high-redshift blazar whose optical radiation is dominated by quasar-like nuclear emission. We here present the results of a spectroscopic...

    Unveiling the Narrow-Line Seyfert 1 Nature of Markarian 573 Using Near-Infrared Spectroscopy
    In this Letter we present clear evidence that Mrk 573 is an obscured narrow-line Seyfert 1 (NLSy1) galaxy and not an archetypal Seyfert 2, as it has been...

    Unveiling the Nature of M94's (NGC4736) Outer Region: A Panchromatic Perspective
    We have conducted a deep multiwavelength analysis (0.15-160 μm) to study the outer region of the nearby galaxy M94. We show that the non-optical data support...

    Unveiling the Nature of the Low Surface Brightness Stellar Host in Blue Compact Dwarf Galaxies
    In order to characterize the low surface brightness component in blue compact dwarf galaxies, we determine their structural parameters for eight objects by...

    Unveiling the shape: A multi-wavelength analysis of the galaxy clusters Abell 76 and Abell 1307
    We analyse the dynamical state of the galaxy clusters Abell 76 and Abell 1307 from the optical point of view, presenting a coherent scenario that responds to...

    Unveiling the sources of disk heating in spiral galaxies with the CALIFA survey
    The stellar velocity ellipsoid (SVE) quantifies the amount of velocity dispersion in the vertical, radial and azimuthal directions. Since different disk heating...
