Abstract

The authors develop a formalism dealing with relativistic radiation hydrodynamics, tailored towards numerical implementation in curvilinear coordinates. This approach allows for numerical calculations even in the presence of coordinate singularities, thereby alleviating a longstanding problem in the field.
