There is a growing new class of young spin-down powered pulsars called GeV-quiet soft gamma-ray pulsar; (1) spectral turnover appears around 10 MeV, (2) the X-ray spectra of below 20 keV can be described by power law with a photon index of around 1.2 and (3) the light curve in X-ray/soft gamma-ray b...
