Detection of 10–100 MeV γ-Rays from the Crab Nebula Pulsar NP 0532

Abstract

Pulsed γ-ray emission from NP 0532 has been detected up to 100 MeV. For the main pulse from 10 to 30 MeV the signal to noise is (5–6σ). The energy spectrum of the main pulse from 1 keV to 100 MeV can be fitted by a single power law of index (−0.9).
