  1. 59. Results from the ANITA Search for Ultra-High Energy Neutrinos
    Mlle Abigail Vieregg (UCLA)
    12/03/2010 17:00
    The ANITA (ANtarctic Impulsive Transient Antenna) experiment is an innovative balloon-borne radio telescope, designed to detect coherent Cherenkov emission from cosmogenic ultra high-energy neutrinos with energy greater than 10^18 eV. The second flight of the ANITA experiment launched on December 21st, 2008, and collected data for 30 days. This new data set allows for the most sensitive...

  2. 27. Results from the Pierre Auger Observatory on Astroparticle Physics
    Dr Sofia Andringa (LIP)
    12/03/2010 17:20
    The Pierre Auger Observatory has already collected more ultra high high energy cosmic ray data than all of the previous experiments. With an hybrid detection technique, it can provide coherent results on the flux, energy spectrum and arrival directions of the highest energy cosmic rays, and characterize the extensive air showers in order to probe the primary particle characteristics and its...

  3. 85. Dark Matter Constraints with the First Year of Fermi LAT Data
    M. Tomi Ylinen (Royal Institute of Technology (KTH))
    12/03/2010 17:45
    Our understanding of the Universe today includes overwhelming observational evidence for the existence of an elusive form of matter that is generally referred to as dark. Although many theories have been developed to describe its nature, very little is actually known about its properties. The launch of the Fermi Gamma-ray Space Telescope in 2008 opened a new window for the indirect...

  4. 63. Higgs in Space
    Geraldine Servant (CERN)
    12/03/2010 18:10
    Theory
    Ordinary
    In some classes of WIMP models, the Higgs boson could be copiously produced in association with a photon from dark matter annihilations in the center of our galaxy. The resulting photon spectrum possesses a line whose energy reflects the mass of the Higgs and of the WIMP and whose intensity depends on the WIMP spin and statistics. I will discuss how gamma-ray telescopes such as Fermi could...

  5. 105. Axions and the transparency of the Universe
    Dr Malcolm Fairbairn (King's College London)
    12/03/2010 18:50
    Theory
    Ordinary
    The propagation of high energy photons across the Universe is hindered by various radiation fields with which they interact. In this talk we will explain how the presence of an axion like particle can change this propagation and make the Universe more transparent. This results in high energy photons making it across cosmic gulfs we would normally not expect them to be able to traverse. We...

  6. 111. Light through the wall (axions) : ALPS and review
    Dr Klaus Ehret (DESY)
    12/03/2010 19:10
    In the last years it has been realized, that extensions of the Standard Model may manifest itself also at meV energy scales. The low energy frontier is a rich complement to the conventional high energy particle physics landscape. The search for this new particles initiated experimental activities around the world. "Light-shining-through-a-wall" experiments search for Weakly Interacting...
