Hydrodynamics and radiation from a relativistic expanding jet with applications to GRB afterglow
edited by: R. M. Kippen, R. S. Mallozzi, G. J. Fishman
We describe fully relativistic three dimensional calculations of the slowing down and spreading of a relativistic jet by an external medium like the ISM. We calculate the synchrotron spectra and light curves using the conditions determined by the hydrodynamic calculations. Preliminary results with a moderate resolution are presented here. Higher resolution calculations are in progress. .
