  • CASSA Workshop 1: Unclouding the Thousand Eyes of an Array Radio Telescope

    Featured
    CASSA, IUB Main Building Rooftop Plot 16, Aftabuddin Ahmed Road, Block B, Bashundhara RA (Main Building Rooftop), Dhaka, Bangladesh

    The most advanced telescopes at radio wavelengths are now Array Radio Telescopes (ART), arrays of hundreds and thousands of radio antennas guarding the universe like Argus in Ovid's Metamorphoses. ARTs are everywhere, from the Y-shaped Very Large Array (VLA) in the deserts of New Mexico to the rectilinear Medicina displayed dramatically in the Red Desert […]
