The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …

We present analysis of the normalized 21-cm bispectrum from fully-numerical simulations of
intergalactic-medium heating by stellar sources and high-mass X-ray binaries (HMXBs) …

In this paper, we establish the accuracy and robustness of a fast estimator for the bispectrum–
the 'FFT-bispectrum estimator'. The implementation of the estimator presented here offers …

Observations of the epoch of reionization give us clues about the nature and evolution of the
sources of ionizing photons, or early stars and galaxies. We present a new suite of structure …

This paper considers the impact of Lyman α coupling and X-ray heating on the 21-cm
brightness-temperature one-point statistics (as predicted by seminumerical simulations). The …

The 21cm line refers to a forbidden transition in neutral hydrogen associated with alignment
of spins of the proton and electron. It is a very low energy transition that is emitted whenever …

We investigate self-shielding of intergalactic hydrogen against ionizing radiation in radiative
transfer simulations of cosmic reionization carefully calibrated with Lyα forest data. While self …

The observed 21 cm signal from the epoch of reionization will be distorted along the line of
sight by the peculiar velocities of matter particles. These redshift-space distortions will affect …

We use the Dark-ages, Reionization And Galaxy formation Observables from Numerical
Simulations (DRAGONS) framework to investigate the effect of galaxy formation physics on …

The redshifted 21 cm-line signal from neutral hydrogen in the intergalactic medium (IGM)
gives a direct probe of the epoch of reionization (EoR). In this paper, we investigate the …
