First results on the high energy cosmic ray electron spectrum from Fermi LAT
Designed as a high-sensitivity gamma-ray observatory, the Fermi Large Area Telescope is also an electron detector with a large acceptance exceeding 2 m2 sr at 300 GeV. Building on the gamma-ray analysis, we have developed an efficient electron detection strategy which provides sufficient background rejection for the measurement of the electron spectrum up to 1 TeV. Our high precision data show that the electron spectrum falls with energy as E-3.04 and does not exhibit prominent spectral feature. Analysis approach and details along with some possible interpretation will be presented
