Magnetic reconnection in realistically turbulent astrophysical environments does not depend on electric conductivity of plasma, but instead is controlled by the degree of turbulent stochasticity of magnetic field lines. Such a reconnection can induce the first order Fermi acceleration of energetic particles. I will show that this acceleration is different in 2D and 3D reconnection with 3D...

1. Angular distribution of energetic particles scattered by strongly anisotropic MHD turbulence: understanding Milagro/IceCube results

Both the acceleration of cosmic rays (CR) in supernova remnant shocks and their subsequent propagation through the random magnetic field of the Galaxy deem to result in an almost isotropic CR spectrum. Yet the MILAGRO TeV observatory and the IceCube discovered sharp (~10 deg) arrival anisotropies of CR nuclei. We suggest a mechanism for producing such a CR beam which operates en route to...

23. Trying to Understand the Interstellar Transport and Resulting Anisotropies of Galactic Cosmic Rays

Prof. J.R. (Randy) Jokipii (University of Arizona)

The observed interstellar anisotropies of galactic cosmic rays, and their energy dependence, are a major source of information concerning their origin and transport in the galaxy. They also present significant challenges to our understanding. I will discuss possible interpretations of some of the anisotropies in terms of interstellar transport in the interstellar magnetic field and...
