The search for primordial gravitational waves through the B-mode polarization pattern in the CMB is one of the major goals of current and future CMB experiments. Besides foregrounds, a potential hurdle in this search is the anisotropic secondary B-mode polarization generated by the scattering of CMB photons off free electrons produced during patchy cosmological reionization. Robust predictions of these secondary anisotropies are challenging because of uncertainties in the reionization history… Expand
Inevitable imprints of patchy reionization on the cosmic microwave background anisotropy
Reionization of the cosmic neutral hydrogen by the first stars in the Universe is an inhomogeneous process which produces spatial fluctuations in free electron density. These fluctuations lead toExpand
CMB constraints on a physical model of reionization
We study constraints on allowed reionization histories by comparing predictions of a physical semi-numerical model with secondary temperature and polarization anisotropies of the cosmic microwaveExpand
The correlation of high-redshift galaxies with the thermal Sunyaev–Zel’dovich effect traces reionization
We explore a potential new probe of reionization: the cross-correlation of high-redshift galaxies with maps of the thermal Sunyaev-Zel'dovich (tSZ) effect. We consider two types of high redshiftExpand
Unified approach to secondary effects on the CMB B-mode polarization.
We develop a systematic and unified approach to estimate all possible secondary (i.e. non-primordial) nonlinear effects to the cosmic microwave background (CMB) polarization, named curve-of-sightExpand
On the accuracy of common moment-based radiative transfer methods for simulating reionization
Modern cosmological simulations of reionization often treat the radiative transfer by solving for the monopole and dipoles of the intensity field and by making some ansatz for the quadrupole momentsExpand


Evidence for Large-Scale Fluctuations in the Metagalactic Ionizing Background Near Redshift Six
The observed scatter in intergalactic Lyman-$\alpha$ opacity at $z \lesssim 6$ requires large-scale fluctuations in the neutral fraction of the intergalactic medium (IGM) after the expected end ofExpand
Is patchy reionization an obstacle in detecting the primordial gravitational wave signal
The large-scale cosmic microwave background (CMB) B-mode polarization is the direct probe to the low-frequency primordial gravitational wave signal. However, unambiguous measurement of this signalExpand
Quantitative Constraints on the Reionization History from the IGM Damping Wing Signature in Two Quasars at z > 7
During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping wing absorption feature on the spectrum of high-redshift quasars. A detection of this signature providesExpand

The Maximum B-mode Polarization of the Cosmic Microwave Background from Inhomogeneous Reionization
We compute the B-mode polarization power spectrum of the CMB from an epoch of inhomogeneous reionization, using a simple model in which H II regions are represented by ionized spherical bubbles withExpand
