Small-scale Anisotropies of Cosmic Rays from Turbulent Flow
Within the classical convection–diffusion approximation, we show that the angular distribution of cosmic rays (CRs) in a highly turbulent flow may exhibit significant small-scale anisotropies. The CR intensity angular power spectrum C _ℓ is then a direct reflection of interstellar turbulence, from w...
