This thesis investigates the cosmic electron spectrum of our galaxy with the MAGIC telescope in the energy range 0.1-2 TeV.
The ATIC experiment measured an increased flux in the electron spectrum between 0.3-0.8 TeV, in contrast to the expected flux from secondary electrons produced in cosmic ray interactions.
Many different interpretations have been proposed as an explanation for these results, such as pulsars or dark matter as additional sources of electrons. Measurements with the Fermi satellite also show an excess of electrons in the spectrum, however, the spectrum is not compatible with the ATIC results. MAGIC measured the electron spectrum which is in agreement with the previous measurements, so that additional sources of cosmic electrons are clearly demonstrated. However, the excess of electrons, which was measured only by ATIC, can neither be confirmed nor excluded due to large statistical uncertainties.
