SUMMARY:Gamma Ray Burst Jet Simulations\, Astronomy Colloquium\, Brian
  Morsony\, UW Astronomy Dept
DESCRIPTION:Gamma Ray Bursts are the most luminous events in the unive
 rse and are associated with the death of massive stars.  GRBs are powe
 red by relativistic jets from a newly-formed compact object at the cen
 ter of a star.  The jet then punches through the outer layers of the s
 tar before eventually emitting gamma-rays.  However\, the extent to wh
 ich passage through the star effects the jet is not well understood.  
 I will present new simulations of propagation and long-term evolution 
 of jets with time-varying central engines and discuss the observationa
 l implications of the results.
