    1. 35. UHECR anisotropies and the Large-Scale matter distribution
      Peter Tinyakov (Universite Libre de Bruxelles (ULB))
      10/12/16, 3:55 PM

      We will discuss the expectations for the UHECR anisotropy under the assumption that the UHECR sources trace the matter distribution in the Universe. The effect of cosmic magnetic fields and charge composition of UHECR will be considered. The experimental signatures and their possible discovery strategies will be discussed.

    2. 4. Monte Carlo Bayesian search for the plausible source of the Telescope Array hotspot
      Hao-Ning He (UCLA)
      10/12/16, 4:20 PM

      The Telescope Array (TA) collaboration has reported a hotspot of 19 ultrahigh-energy cosmic rays (UHECRs). Using a universal model with one source and energy-dependent magnetic deflections, we show that the distribution of the TA hotspot events is consistent with a single source hypothesis, although multiple sources cannot be ruled out. The chance probability of this distribution arising from...

    3. 17. A Close Correlation of TA Hotspot Events with Filaments of Galaxies Connected to the Virgo Cluster
      Dongsu Ryu (UNIST)
      10/12/16, 4:40 PM

      The hotspot feature of ultra-high-energy cosmic rays (UHECRs) was reported by the Telescope Array (TA) experiment in 2014. To study the nature and origin of the TA hotspot, we search structures in the local universe, within 50 Mpc. We identify filaments of galaxies around the TA hotspot area, which are connected to the Virgo cluster. By the anisotropy test, we find a close correlation of the...

    4. 18. Influence of the galactic magnetic field on the trajectory of ultra-high energy cosmic rays
      Dr Jihyun Kim (Ulsan National Institute of Science and Technology)
      10/12/16, 5:00 PM

      The trajectory of ultra-high-energy cosmic rays (UHECRs) is affected by the galactic magnetic field (GMF). The GMF has been extensively studied, but the GMF toward the high galactic latitude is yet uncertain. Assuming the deflection of UHECR trajectory by the GMF is mainly dependent on the galactic latitude, b, we analyze the correlation between the arrival direction distribution of UHECRs...

    5. 52. Nonlinear Diffusive Shock Acceleration in GRB Afterglows
      Don Warren (RIKEN)
      10/12/16, 5:20 PM

      The standard synchrotron afterglow model has been applied to enormous success since its original formulation. In spite of the variety of extensions and refinements made to the basic model, virtually all work on GRB afterglows has ignored two critical aspects of shock acceleration. First, it ignores the significant population of thermal particles that must be present downstream but are not...
