Week 8: Evolution of Perturbations

  • Published 2017


We will follow Ch. 6 in Weinberg’s book quite closely. As seen therein, the exact calculations for the evolution of radiation perturbations require that we take into account the fact that Thomson scattering of photons depends on the photon polarization. To simplify and get to the basic physics results, we will assume that photons are unpolarized and that… (More)
