Cosmic-Ray Electron Anisotropy Searches with the Fermi Large Area Telescope
Abstract
The Fermi Large Area Telescope (Fermi-LAT) provides unique high statistics for high-energy cosmic-ray electrons (CREs), with excellent angular resolution. Any anisotropies in the arrival directions of these CRE could potentially be a signature of electrons originating in a nearby source (for energies high enough to avoid heliospheric effects and also depending on the properties of the Galactic magnetic field between us and the source) and could provide information not only on the source parameters and location but also on the solar and Galactic magnetic-field structures. We will present the preliminary results and details of a search for anisotropies in the Cosmic-Ray Electron data of the Fermi-LAT.
