On the evolution of the Gamma- and X-ray luminosities of Pulsar Wind Nebulae (2008)
Mattana, Fabio, Falanga, Maurizio, Götz, Diego, Terrier, Régis, Esposito, Paolo, Pellizzoni, Alberto, ...
Pulsar wind nebulae are a prominent class of very high energy (E > 0.1 TeV) Galactic sources. Their Gamma-ray spectra are interpreted as due to inverse Compton scattering of ultrarelativistic...
