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...

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...

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...
