Since the launch of the Fermi/LAT telescope in June 2008, several hundred radio-loud gamma-ray pulsars have been detected. Observing simultaneously their radio and gamma-ray pulse profiles helps to constrain the geometry and radiation mechanisms within their magnetosphere and to localize the photon production sites. In this talk I show how time-aligned gamma-ray light curve fitting of young...

In this talk, we will review the synchro-curvature modeling of high-energy radiation from pulsars. Through a minimalist model containing only three essential free parameters, the model is able to fit the spectra of the entire population of pulsars, showing trends between the magnitude of the electric field and the parameter associated to the typical lengthscale of the acceleration region. We...

A number of pulsars have now been detected by ground-based Cherenkov telescopes, including PSR B1706-44, Geminga, Crab, and Vela. Vela exhibits a TeV component that is distinct from its GeV one, in contrast to the other detected pulsars. In the synchro-curvature radiation / inverse Compton (SCR-IC) framework, the same particles that are responsible for the GeV emission via SCR (with Lorentz...
