ROSAT observations of the Vela pulsar and its surroundings revealed a collimated X-ray feature almost 45 in length (Markwardt & Ögelman 1995), interpreted as the signature “cocoon” of a one-sided jet from the Vela pulsar. We report on a new ASCA observation of the Vela pulsar jet at its head, the point where the jet is believed to interact with the supernova remnant. The head is clearly detecte...

ABSTRACT We have simulated the evolution of non-thermal cosmic ray electrons (CREs) in 3D relativistic magneto hydrodynamic (MHD) jets evolved up to a height 9 kpc. The CREs been space and energy concurrently with jet fluid, duly accounting for radiative losses acceleration at shocks. show that stable MHD instabilities expected trends regular flow spine hotspot followed by settling backflow. Ho...
