4. UHE photons, neutrinos, and hadrons at the Pierre Auger Observatory: Current status and prospects for the future

Prof. David Nitz (Michigan Technological University)

Cosmic Rays (Theory/Experiment) Parallel

The status of searches for UHE photons and neutrinos at the Pierre Auger Observatory will be presented. Current limits will be compared to both models and other measurements. Evidence of the composition of the highest energy cosmic rays will be presented, and implications for photons and neutrino searches will be discussed. Plans for an upgrade of the Observatory to improve composition...

Cosmic Rays (Theory/Experiment) Parallel

The Telescope Array (TA) is the largest experiment in the northern hemisphere studying ultrahigh energy cosmic rays. It is located in Utah, USA, and has been collecting data since 2008. Results will be presented on the spectrum of cosmic rays, their composition, searches for gamma ray and neutrino primaries, and searches for anisotropy in their arrival directions. In addition, new projects...

35. TARA: Radar Detection of UHECR Air Showers

Cosmic Rays (Theory/Experiment) Parallel

While the possibility of detecting the radar echoes of extensive air showers (EAS) has been discussed since the 1940's, there has been no conclusive evidence for RF scattering from EAS ionization columns to date. The Telescope Array Radar (TARA) project is by far the most ambitious effort ever undertaken to confirm the existence of this phenomenon. TARA employs two 20 kilowatt VHF television...

17. Cosmic Rays of Extreme Energies

Prof. Angela Olinto (The University of Chicago)

Cosmic Rays (Theory/Experiment) Parallel

After a century of observations, the origin of cosmic rays is still a mystery. At the highest energies, sources should be among the most powerful extragalactic sources and primaries should point back to their sources. Extremely energetic cosmic rays (EECRs) reach interaction energies orders of magnitude beyond the LHC and probe the frontiers of particle physics. Possible explanations for their...
