  "abstract": "Turbulent motion of the background plasma can introduce fluctuations in the spatial distribution of cosmic rays (CRs). For an ensemble-averaged Gaussian CR distribution with a width $ Λ\\left( t,p \\right) $ at time $ t $ and momentum $ p $, it is found that $ P_\\text{s}\\left( t,k,p \\right) $ and $ P_\\text{d}\\left( t,k,p \\right) $, the fluctuation power spectra induced by incompressible and acoustic turbulent convection, respectively, have power-law asymptotics in wavenumber $ k $: $ P_\\text{s}\\left( t,k,p \\right) \\propto k^4 $ and $ P_\\text{d}\\left( t,k,p \\right) \\propto k^2 $ for $ k\\ll 1/Λ\\left( t,p \\right) $; $ P_\\text{s}\\left( t,k,p \\right) \\propto k^{γ_\\text{s}-4} $ for $ k\\gg 1/L_\\text{s} $, and $ P_\\text{d}\\left( t,k,p \\right) \\propto k^{γ_\\text{d}-2} $ for $ k\\gg 1/L_\\text{d} $, where $ γ_\\text{s} $ and $ γ_\\text{d} $ are the spectral indices of the velocity power spectra of the incompressible and acoustic turbulence below their outer scales $ L_\\text{s} $ and $ L_\\text{d} $, respectively. These results have implications for probing interstellar turbulence via future high-resolution images of pulsar gamma-ray halos.",
