Cosmological Radiative Transfer Comparison Project II: The Radiation-Hydrodynamic Tests

Understand

The development of radiation hydrodynamical methods that are able to follow gas dynamics and radiative transfer self-consistently is key to the solution of many problems in numerical astrophysics.

• Such fluid flows are highly complex, rarely allowing even for approximate analytical solutions against which numerical codes can be tested.
• An alternative validation procedure is to compare different methods against each other on common problems, in order to assess the robustness of the results and establish a range of validity for the methods.
• Previously, we presented such a comparison for a set of pure radiative transfer tests (i.e.
