We study the signal from patchy reionization in view of the future high accuracy polarization measurements of the Cosmic Microwave Background (CMB). We implement an extraction procedure of the patchy reionization signal analogous to CMB lensing. We evaluate the signal to noise ratio (SNR) for the future Stage IV (S4) CMB experiment. The signal has a broad peak centered on the degree angular scales, with a long tail at higher multipoles. The CMB S4 experiment can effectively constrain the… 

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 signal

Detectability of the τes−21cm cross-correlation: a tomographic probe of patchy reionization

The cross-correlation between fluctuations in the electron scattering optical depth τes as probed by future Cosmic Microwave Background (CMB) experiments, and fluctuations in the 21cm differential

Revised estimates of CMB B-mode polarization induced by patchy reionization

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

Beyond Optical Depth: Future Determination of Ionization History from the Cosmic Microwave Background

The fundamental limits to which reionization histories can be constrained using only large-scale cosmic microwave background (CMB) anisotropy measurements are explored and future high signal-to-noise measurements of the multipoles 10 ⩽ ℓ < 20 are especially important for breaking the degeneracy between x e min and z re.

Reionization inference from the CMB optical depth and E-mode polarization power spectra

The Epoch of Reionization (EoR) depends on the complex astrophysics governing the birth and evolution of the first galaxies and structures in the intergalactic medium. EoR models rely on cosmic

Reconstructing Patchy Reionization with Deep Learning

A convolutional neural network, ResUNet-CMB, that is capable of the simultaneous reconstruction of two sources of secondary CMB anisotropies, gravitational lensing and patchy reionization and significantly outperforms the quadratic estimator at low noise levels.

The bispectrum of polarized galactic foregrounds

Understanding the properties of the galactic emission at millimetre wavelengths is important for studies of the cosmic microwave background (CMB). In this work we explore the bispectrum, the harmonic

Reconstructing cosmic polarization rotation with ResUNet-CMB

The ResUNet-CMB convolutional neural network is extended to reconstruct anisotropic cosmic polarization rotation in the presence of gravitational lensing and patchy reionization, and it is shown that the network simultaneously reconstructs all three effects with variance that is lower than that from the standard quadratic estimator nearly matching the performance of an iterative reconstruction method.

Cosmology with Rayleigh scattering of the cosmic microwave background

The cosmic microwave background (CMB) has been a treasure trove for cosmology. Over the next decade, current and planned CMB experiments are expected to exhaust nearly all primary CMB information. To
