The Boltzmann Equation - University of Chicago

In other words, the phase space density of photons is conserved along its trajectory. The gravitational e ects are hidden in the time dependence of the photon momentum. The solution to equation (2.2) is non-trivial since the photons propagate in a metric distorted by the lumpy distribution of matter. To evaluate its e ect explicitly, we need to ...
