Pulsars in Gamma Rays: What Fermi Is Teaching Us
Abstract
The 2nd Fermi-LAT pulsar catalog includes 117 gamma-ray pulsars, of which roughly one third are millisecond pulsars (MSPs) while the remaining two thirds split evenly into young radio-loud and radio-quiet pulsars. Although this large population will enable future, detailed studies of emission mechanisms and the evolution of the underlying neutron star population, some nearly-universal properties are already clear and unequivocal. We discuss some of these aspects below, including the altitude of the gamma-ray emission site and the shape of the gamma-ray spectrum and its implications for the radiation mechanism.
