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 to observable signatures in cosmological probes like the cosmic microwave background (CMB). We explore the effect of the electron density fluctuations on CMB using photon-conserving semi-numerical simulations of reionization named \texttt{SCRIPT}. We show that the amplitude of the kinematic Sunyaev…

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.
