Descripción
Space-based gamma-ray observations have established sharp cutoffs at a few GeV as a common feature of pulsar emission, with the Crab pulsar until recently the only source detected above 100 GeV. Observations with imaging atmospheric Cherenkov telescopes (IACTs), such as H.E.S.S., now reveal pulsar spectra extending up to tens of TeV. For the Vela pulsar, we detect a distinct radiation component reaching at least 20 TeV, providing clear evidence that pulsars can accelerate particles to Lorentz factors above 4 × 10^7. I will present the latest VHE pulsar results and discuss their implications for models of particle acceleration and emission in pulsar magnetospheres.
