The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

The observation of a broad excess of sub-TeV cosmic rays compatible with the direction of the heliospheric tail (Nagashima et al. 1998) and the discovery of two significant localized excess regions of multi-TeV cosmic rays by the MILAGRO collaboration (Abdo et al. 2008), also from the same region of the sky, have raised questions on their origin. In particular, the coincidence of the most significant localized region with the direction of the heliospheric tail and the small angular scale of the observed anisotropy (~ 10deg) is suggestive a local origin and of a possible connection to the low energy broad excess. Cosmic ray acceleration from magnetic reconnection in the magnetotail is proposed as a possible source of the energetic particles.

Several sources of the CR excess have been considered, including strong-scattering of local protons [ref] , neutron emission from nearby gas in the heliosphere [ref] , and multiple supernova remnants with stochastic particle propagation [ref] .

The TeV Cosmic-Ray Anisotropy from Local Dark Matter Annihilation · Introduction · 0.93
Magnetic reconnections in the heliotail [ref] , non-isotropic particle transport in the heliosheath [ref] or the heliospheric electric field structure [ref] have also been considered as a source of these small-scale anisotropies.

Anomalous Anisotropies of Cosmic Rays from Turbulent Magnetic Fields · Introduction · 0.96
There are several theories regarding the possible origin of this anisotropy including ones that postulate a heliospheric origin [ref] though it is also possible that the origin of anisotropy is due to characteristics of the interstellar magnetic field at distances less than 1 parsec or even the diffuse flow of nearby galactic sources [ref] .
