Our choice of hydrodynamic formalism is Carter\u2019s two-fluid theory, which happens to coincide with \u00d6ttinger\u2019s GENERIC theory for relativistic heat conduction. This is a natural framework, as it should correctly describe the relativistic \u201cinertia of heat\u201d as well as the subtle interplay between reversible and irreversible couplings.
