Reionization and cosmic microwave background distortions: A complete treatment of second-order Compton scattering.
The ionization history of the universe provides a major source of ambiguity in constraining cosmological models using small angular scale microwave background anisotropies. To clarify these issues, we consider a complete treatment of Compton scattering to second order, an approach which may be applicable to other astrophysical situations. We find that only the O(v) Doppler effect, and the O(vδ)...
متن کاملPolarization of the Cosmic Microwave Background from Non-Uniform Reionization
We study the polarization anisotropy in the Cosmic Microwave Background (CMB) resulting from patchy reionization of the IGM by stars in galaxies. It is well known that the polarization of the CMB is very sensitive to the details of reionization, including the reionization epoch and the density fluctuations in the ionized gas. We calculate the effects of reionization by combining a semi-analytic...
متن کاملInhomogeneous Reionization and the Polarization of the Cosmic Microwave Background.
In a universe with inhomogeneous reionization, the ionized patches create a second-order signal in the cosmic microwave background polarization anisotropy. This signal originates in the coupling of the free-electron fluctuation to the quadruple moment of the temperature anisotropy. We examine the contribution from a simple inhomogeneous reionization model and find that the signal from such a pr...
متن کاملReionization Revisited: Secondary Cosmic Microwave Background Anisotropies and Polarization
Secondary cosmic microwave background (CMB) anisotropies and polarization provide a laboratory for studying structure formation in the reionized epoch. We consider the kinetic Sunyaev-Zeldovich e†ect from mildly nonlinear large-scale structure and show that it is a natural extension of the perturbative Vishniac e†ect. If the gas traces the dark matter to overdensities of order 10, as expected f...
