Observation of Gamma Rays from the Galactic Center with the MAGIC Telescope

Abstract

Recently, the Galactic center has been reported to be a source of very high energy (VHE) g-rays by the CANGAROO, VERITAS, and HESS experiments. The energy spectra as measured by these experiments show substantial differences. In this Letter we present MAGIC observations of the Galactic center, resulting in the detection of a differential g-ray flux consistent with a steady, hard-slope power law, described as cm 2 s 1 TeV 1 . The g-ray source is centered at (R.A.,
