cosmic microwave background polarization


/Parent 35 0 R Polarization of the cosmic microwave background, though not yet detected, provides a source of information about cosmological parameters complementary to temperature fluctuations.
We begin with production of polarization by Thomson scattering. One involves the sum of the masses of all the cosmic neutrinos that incessantly stream through space. 6 0 obj

Marcelin Berthelot, 75231 Paris Cedex 05, FRANCE and (UMR 7164 CNRS, Universite Paris 7, CEA, Observatoire de Paris)´ Received on 15 May, 2006 Cosmic microwave background (CMB) studies underpin our understanding of the universe and its history. endobj This very faint radiation, left over from a time – about 400,000 years after the Big Bang – when enough neutral atoms had formed to let light travel freely, is the closest thing science has to a panoramic snapshot of the contents of the cosmos as it was taking shape. Scalar perturbations create density perturbations.
