    Solar core rotation
    Data from solar line of sight velocity measurements are presented to demonstrate the existence of a synodic signal with a 6.5 m/sec amplitude. Recordings of...

    Spectrum of the cosmic background radiation between 3 MM and 800 microns
    The measurements reported were made during a flight to an altitude of 40 km, on Mar. 13, 1974. A polarizing Michelson interferometer cooled, by a liquid helium...

    Stars Within the Large Magellanic Cloud as Potential Lenses for Observed Microlensing Events
    MASSIVE compact objects in the Galactic halo, known as MACHOs, have been postulated as the origin of a substantial fraction of the 'dark matter' known to exist...
