We simulate experiments performed with the Falcon laser at Lawrence Livermore National Laboratory to generate strong blast waves expanding in cylindrical geometry of relevance to astrophysics. In particular, we are interested in producing and modeling radiative shocks. Our goal is to develop a laboratory setting for studying radiative shocks of relevance to supernova remnants. In previous work we have demonstrated that it is possible to generate radiative shocks in the laboratory. In additions, we have shown how we can determine the energy-loss rate of the shock from the blast wave evolution using a simple analytic method that is independent of the details of radiative cooling and is scalable to both the laboratory and astrophysical blast waves. Our current work deals with instabilities associated with radiative blast waves and their application to the laboratory and to astrophysics. We examine some of the previous work done in the area of radiative instabilities in supernova remnants and discuss the challenges of adapting this work to the laboratory setting.
