Description
The pulsed radiation from PSR B0833-45 (Vela) has a phased-averaged spectral
energy distribution of an apparently simple structure across a wide energy range.
However, in narrow energy bands the pulses reveal astonishing complexity of
the directional pattern of the radiation. We present the results of a 3D modeling
of the Vela radiation properties in the outer-gap scenario.
We show how the synchrotron emission as well as the inverse Compton scattering (ICS)
of soft photons by secondary e$^\pm$-pairs in its magnetic and non-magnetic
regimes reproduces qualitatively, and in some cases quantitatively, the observed
energy-dependent pulses of Vela.
Moreover, we present how ICS of soft synchrotron photons by primary particles can
form a pulsed spectral component in the VHE domain. The flux of this component
should be of interest to the Cherenkov Telescope Array.
