<strong>Pulsar</strong> <strong>Wind</strong> <strong>Nebulae</strong> (PWNe)•<strong>Pulsar</strong> <strong>Wind</strong> <strong>Nebulae</strong> :–Relativistic particles (e ± ) injected bythe central pulsar–Ejecta <strong>of</strong> the supernova sweeps up–Flow decelerated at the shock–Particles accelerated at the shock(Diffusive Shock Acceleration)–Non-thermal photons emitted by : Synchrotron Bremsstrahlung Inverse Comptonscattering (leptonicscenario) Pion decay (hadronicscenario)•High energy observations can help constraining the properties <strong>of</strong> thePWN (age, injection spectrum, maximum particle energy and breaks,nebular magnetic field, ambient photon field, etc.)(Gaensler & Slane, 2006, ARA&A, 44, 17)M.-H.
