The modeling of the Vela pulsar pulses - from optical to hard gamma-ray energy

The pulsed radiation from PSR B0833-45 (Vela) has a phased-averaged spectral energy distribution
(SED) of an apparently simple structure across a wide energy range, from optical light to hard gamma-rays.
However, the Vela pulses in narrow energy bands reveal astonishing complexity of the directional
pattern of the radiation. These pulses are, therefore, a unique clue to the underlying radiative processes.
We present the results of a 3D modeling of the Vela radiation properties within an outer-gap scenario.
We show how the inverse Compton scattering of photons by primary and secondary particles
in its magnetic and non-magnetic regimes reproduces qualitatively, and in some cases quantitatively,
the observed energy-dependent pulses of Vela.
