    Upper Limit for γ-Ray Emission above 140 GeV from the Dwarf Spheroidal Galaxy Draco
    The nearby dwarf spheroidal galaxy Draco, with its high mass to light ratio, is one of the most auspicious targets for indirect dark matter (DM) searches...

    Upper limits from the LIGO and TAMA detectors on the rate of gravitational-wave bursts
    We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodeled gravitational-wave...

    Upper Limits on a Stochastic Background of Gravitational Waves
    The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We...

    Upper limits on gravitational wave bursts in LIGO's second science run
    We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency...

    Upper Limits on the VHE Gamma-Ray Emission from the Willman 1 Satellite Galaxy with the Magic Telescope
    We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May...

    Upper Limits to the Magnetic Field in Central Stars of Planetary Nebulae
    More than about 20 central stars of planetary nebulae (CSPNs) have been observed spectropolarimetrically, yet no clear, unambiguous signal of the presence of a...

    Uranian ring orbits from earth-based and Voyager occultation observations
    The authors have combined an enhanced Earth-based occultation data set and Voyager occultation observations to determine a new solution for the ring orbital...
