A broad range of models have been proposed to explain these anisotropies ranging from finite-scale magnetic field structures to dark matter annihilation. The standard diffusion transport methods used in cosmic ray propagation do not capture the transport physics in a medium with finite-scale or coherent magnetic field structures. Here, we present a Monte Carlo transport method, applying it to a series of finite-scale magnetic field structures to determine the requirements of such fields in explaining the observed cosmic ray,small-scale anisotropies.", "revisions": [ { "version": "v1", "updated": "2021-01-19T17:59:10.000Z" } ], "analyses": { "keywords": [ "cosmic ray transport", "mixed magnetic fields", "finite-scale magnetic field structures", "monte carlo transport method", "average cosmic ray flux" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
