Abstract
More than a hundred pulsars have been detected by the Fermi gamma-ray observatory, showing similar spectral characteristics and cutoffs in a narrow range, around a few GeV. The high energy emission is thought to come from outer magnetospheric gaps, however radiation from the equatorial current sheet which separates the two magnetic hemispheres far outside the light cylinder has also been investigated in the past. We discuss the "near wind" region, defined as the region starting outside the light cylinder (at radius rLC), and spanning to radius r/rLC = R<Γ. Synchrotron radiation from thermal particles in the current sheet in that region can dominate the gamma-ray emission, leading to cutoffs, luminosities and spectra that are similar to the ones observed by the LAT.
