The Guitar nebula's pulsar appears to accelerate electrons to within ~3/4 of the theoretical maximum potential, and its brightness is best explained by the pulsar crossing an old supernova remnant's compressed, magnetized shell.
In the unscreened-field case, Schwinger pair creation supplies charges far exceeding the Goldreich-Julian rate and removes ~90% of rotational energy within 30 ms for B_p=10^14 G and P_0=1 ms, suppressing gravitational-wave losses and linking millisecond magnetars to the observed population.
Hadronic pp collisions dominate pair loading via pion cascades in magnetar-like outflows from neutron star mergers, channeling magnetic energy into e± and seeding neutrinos up to ~300 MeV.
