Particle Acceleration under Shock-Reconnection Interaction

M. Hoshino (University of Tokyo)

In many astrophysical objects, non-thermal particles are believed to be 
generated not only by shock waves of powerful super sonic outflows but also 
magnetic reconnection of the magnetized plasma outflows.  These include 
pulsars, gamma-ray burst, and the jets from active galactic nuclei.  In the 
pulsar wind-nebula case, it is highly believed that many current sheets are 
embedded in the upstream pulsar wind region, and those current sheets 
transported with the outflow plasmas can intact with the standing shock 
wave existing between the pulsar wind and the synchrotron nebula.  We 
discuss the interaction of shock and current sheet is important for 
generating the non-thermal particles.
