The passage around this formula

The horizon papers supply a curved-spacetime mechanism for changing ν\nu . Danielson, Satishchandran, and Wald describe the conditional long-range fields as sourcing distinct coherent states of the radiation. Radiation reaching the horizon is a genuine independent degree of freedom rather than a merely constrained Coulomb field, so slow recombination cannot…
