Observational Limits on Patchy Reionization: Implications for B-modes
The recent detection of secondary CMB anisotropy by the South Pole Telescope places a conservative bound on temperature fluctuations from the optical depth-modulated Doppler effect of T3000 < √ 13μK at multipoles l ∼ 3000. This bound is the first empirical constraint on reionization optical depth fluctuations at arcminute scales, τ3000 = 0.001 T3000/μK, implying that these fluctuations are no m...
متن کاملHave We Detected Patchy Reionization in Quasar Spectra?
The Lyα forest at z & 5.5 shows strong scatter in the mean transmission even when smoothed over very large spatial scales, & 50 Mpc/h. This has been interpreted as a signature of strongly fluctuating radiation fields, or patchy reionization. To test this claim, we calculate the scatter arising solely from density fluctuations, with a uniform ionizing background, using analytic arguments and sim...
متن کاملLight cone effect on the reionization 21-cm signal – II. Evolution, anisotropies and observational implications
Measurements of the H I 21-cm power spectra from the reionization epoch will be influenced by the evolution of the signal along the line-of-sight direction of any observed volume. We use numerical as well as seminumerical simulations of reionization in a cubic volume of 607Mpc across to study this so-called light-cone effect on the H I 21-cm power spectrum. We find that the light-cone effect ha...
متن کاملProbing patchy reionization through tau-21cm correlation statistics
We consider the cross-correlation between free electrons and neutral hydrogen during the epoch of reionization. The free electrons are traced by the optical depth to reionization τ while the neutral hydrogen can be observed through 21 cm photon emission. As expected, this correlation is sensitive to the detailed physics of reionization. Foremost, if reionization occurs through the merger of rel...
متن کاملSmall-scale Cmb Temperature and Polarization Anisotropies Due to Patchy Reionization
We study contributions from inhomogeneous (patchy) reionization to arcminute scale (1000 < l < 10, 000) cosmic microwave background (CMB) anisotropies. We show that inhomogeneities in the ionization fraction, rather than in the mean density, dominate both the temperature and the polarization power spectra. Depending on the ionization history and the clustering bias of the ionizing sources, we f...
