    Visible spectroscopy of the Sulamitis and Clarissa primitive families: a possible link to Erigone and Polana
    The low-inclination (i 8∘) primitive asteroid families in the inner main belt, that is, Polana-Eulalia, Erigone, Sulamitis, and Clarissa, are considered to be...

    VLBI imaging of the gravitational lens MG J0414+0534
    We observed the quadruple gravitationally lensed image of MG J0414+0534 on 23 November 1997 with a global VLBI array at 8.4 GHz. We report wide-field imaging...

    VLT adaptive optics imaging of QSO host galaxies and their close environment at z ˜ 2.5: Results from a pilot program
    We report on ESO-VLT near-IR adaptive optics imaging of one radio-loud (PKS 0113-283) and two radio quiet (Q 0045-3337 and Q 0101-337) quasars at z > 2. In the...

    VLT-VIMOS integral field spectroscopy of luminous and ultraluminous infrared galaxies. I. The sample and first results
    Context: (Ultra)Luminous Infrared Galaxies [(U)LIRGs] are much more numerous at cosmological distances than locally, and are likely the precursors of elliptical...
