Examing the Rayleigh-Taylor instability in GRB outflow using wavelets

In the gamma ray burst afterglow model, a relativistic shell forms which is unstable to the Rayleigh-Taylor instability during the formation of a relativistic blastwave. This instability is likely observable, and understanding the resulting turbulence have motivated many previous studies into the Rayleigh-Taylor instability in the context of a relativistic fireball. We study the Rayleigh-Taylor instability in a relativistic gamma ray burst outflow with and without magnetic fields. We also examine the growth of the magnetic fields with different Lorentz factors. The simulations are performed using a wavelet based adaptive mesh refinement method.
