Bootstrapping from inflationary magnetogenesis to CMB initial conditions
  The temperature and polarization anisotropies of the Cosmic Microwave
Background are analyzed under the hypothesis that the same inflationary seed
accounting for protogalactic magnetism also affects the Einstein-Boltzmann
hierarchy whose initial conditions are assigned for typical correlation scales
larger than the Hubble radius after matter-radiation equality but before
decoupling. Since the primordial gauge spectrum depends on a combination of
pivotal parameters of the concordance model, the angular power spectra of the
temperature and of the polarization are computed, for the first time, in the
presence of a putative large-scale magnetic field of inflationary origin and
without supplementary hypotheses.
