Gamma-ray burst afterglow broadband fitting based directly on hydrodynamics simulations

23 Oct 2011H. J. van EertenA. J. van der HorstA. I. MacFadyen

We present a powerful new tool for fitting broadband gamma-ray burst afterglow data, which can be used to determine the burst explosion parameters and the synchrotron radiation parameters. By making use of scale invariance between relativistic jets of different energies and different circumburst medium densities, and by capturing the output of high-resolution two-dimensional relativistic hydrodynamical (RHD) jet simulations in a concise summary, the jet dynamics are generated quickly...
