    Virgo's Intracluster Globular Clusters as Seen by the Advanced Camera for Surveys
    We report the discovery of four candidate intracluster globular clusters (IGCs) in a single deep HST ACS field of the Virgo Cluster. We show that each cluster...

    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 diffraction-limited imaging at 11 and 18μm of the nearest active galactic nuclei
    Mid-infrared (mid-IR) imaging at resolutions of 300mas of the central kpc region of 13 nearby, well-known active galaxies is presented. The bulk of the mid-IR...
