Abstract:
The Crab pulsar is the only astronomical pulsed source detected at
very high energy (VHE, E>100GeV) gamma rays. The emission mechanism
of VHE pulsation is not yet fully understood, although several
theoretical models have been proposed.
In order to test new models, we measured the light curve and the
spectra of the Crab pulsar with high precision by means of deep
observations.
We analyzed 135h of selected MAGIC data taken between 2009 and 2013
in stereoscopic mode. In order to discuss the spectral shape in
connection with lower energies, 5.5 years of Fermi-LAT data were also
analyzed
