The multicomponent model of the Crab pulsar at energies above 25 GeV.

CAMPANA R., MASSARO E., MINEO T. and CUSUMANO G.

Abstract (from CDS):

We review a proposed multicomponent model to explain the features of the pulsed emission and spectrum of the Crab Pulsar, in the light of the recent detection of pulsed emission above 25GeV from the MAGIC atmospheric Cerenkov telescope. This model explains the evolution of the pulse shape and of the phase-resolved spectra, ranging from the optical/UV to the GeV energy band, on the assumption that the observed emission is due to several components, which have spectra modelled as log-parabolic laws. We show that the new MAGIC data are well consistent with the predictions of our model.
