    ANITA PRL Cover - October 8, 2010

    Observation of Ultra-high-energy Cosmic Rays with the ANITA Balloon-borne Radio Interferometer Locations of direct (black) and reflected (red) detection of ultrahigh energy cosmic ray events by the ANITA balloon experiment over Antarctica. The field of view is delineated by the dashed blue line. Physical...

    Ultra-Relativistic Magnetic Monopole Search with the ANITA-II Balloon-borne Radio Interferometer

    by  • July 16, 2010 • Publications

    publication-icon

    We have conducted a search for extended energy deposition trails left by ultra-relativistic magnetic monopoles interacting in Antarctic ice. The non-observation of any satisfactory candidates in the 31 days of accumulated ANITA-II flight data results in an upper limit on the diffuse flux of relativistic monopoles. We obtain a 90% C.L. limit of order...

    Observational constraints on the ultrahigh energy cosmic neutrino flux from the second flight of the ANITA experiment

    by  • May 19, 2010 • Publications

    publication-icon

    The Antarctic Impulsive Transient Antenna (ANITA) completed its second long-duration balloon flight in January 2009, with 31 days aloft (28.5 live days) over Antarctica. ANITA searches for impulsive coherent radio Cherenkov emission from 200 to 1200 MHz, arising from the Askaryan charge excess in ultra-high energy neutrino-induced cascades within Antarctic ice. This flight included...

    Observation of Ultra-high-energy Cosmic Rays with the ANITA Balloon-borne Radio Interferometer

    by  • May 12, 2010 • Publications

    publication-icon

    We report the observation of sixteen cosmic ray events of mean energy of 1.5 × 10^19 eV, via radio pulses originating from the interaction of the cosmic ray air shower with the Antarctic geomagnetic field, a process known as geosynchrotron emission. We present the first ultra-wideband, far-field measurements of the radio spectral density of...

    The Antarctic Impulsive Transient Antenna Ultra-high Energy Neutrino Detector Design, Performance, and Sensitivity for 2006-2007 Balloon Flight

    by  • December 10, 2008 • Publications

    publication-icon

    We present a detailed report on the experimental details of the Antarctic Impulsive Transient Antenna (ANITA) long duration balloon payload, including the design philosophy and realization, physics simulations, performance of the instrument during its first Antarctic flight completed in January of 2007, and expectations for the limiting neutrino detection sensitivity. Neutrino physics results will...
