The mechanics of a radiative shock which has “collapsed,” or been compressed to high density, via radiative cooling is discussed. This process is relevant to an experiment in xenon gas that produced a driven, radiatively collapsed shock, and also

This paper presents a validation test of the flux-limited diffusion (FLD) approximation for radiation hydrodynamics in the intermediate optical depth regime. We use an implementation of FLD in the ZEUS-2D astrophysical fluid dynamics code and the res

Radiative shocks (RS) occur in astrophysical systems and in high-energy density laboratory experiments. Aided by three dimensionless parameters, we propose a classification of RS into four types, integrating previous work that has focused independent

Summary form only given. Our group has been studying radiative shocks using laser targets that contain a gas, most often xenon. Our motivation includes the production of conditions in the laboratory relevant to astrophysical phenomena and astrophysic

Our laboratory studies of radiative shocks include development of the semi‐analytic theory that corresponds to various cases of interest to experiments, development of experiments, comparison of experiments and simulations, and drawing connections

Summary form only given. Radiative shocks occur in many high-energy density explosions, but prove difficult to create in laboratory experiments or to fully model with astrophysical codes. Here we describe an experiment significant to astrophysical sh

We have obtained a Thomson scattering spectrum in the collective regime by scattering a probe beam from a shock front, in an experiment conducted at the Omega laser at the Laboratory for Laser Energetics. The probe beam was created by frequency conve
