Studying the dynamics of astrophysical jets is important in order to understand the details revealed by astronomical observations of these sources[1]. In some systems, radiation losses are important to the dynamics. Using the LLNL Nova laser facility, we accelerate gold jets to velocities of order several x 107cm/sec with direct laser illumination on cones. Simulations of the Au jet show strong radiative cooling effects. Initial experiments have been done to test this prediction, and comparisons of 2-D LASNEX simulations with experiment will be shown. We will present simulations of radiation driven cones and hemispheres with various z materials with and without radiation cooling.
