(contribution withdrawn) Observations of the Crab pulsar with the MAGIC telescope — •Takayuki Saito¹, Gianluca Giavitto², Stefan Klepser², Thomas Schweizer¹, Eckart Lorenz^1,3, Razmick Mirzoyan¹, and Masahiro Teshima¹ — ¹Max-Planck-Institut fuer Physik, Muenchen, Germany — ²IFAE, Barcelona, Spain — ³ETH, Zurich, Switzerland

The Crab Pulsar has been detected by MAGIC both in mono-mode and in stereo mode. The mono-mode observations measure the energy spectrum from 25 GeV to 100 GeV, while the stereo mode observations covers from 50 GeV to 400 GeV. The measured energy spectrum deviates significantly from the exponential cutoff spectrum which had been inferred from the Fermi-LAT observations. Here we report on the detail of the observations from 2007 to 2011 and theoretical interpretation of the measured spectrum.
