The epoch of reionization probes the state of our universe when the very first stars formed
and ionized the hydrogen atoms in the surrounding medium. Since the epoch has not yet …

The matter power spectrum is only weakly constrained on subgalactic scales, while physics
beyond the Standard Model can leave unique imprints, especially on sub-parsec scales. We …

We present a forecast of the cosmological parameter estimation using fast radio bursts
(FRBs) from the upcoming Square Kilometre Array (SKA), focusing on the issues of dark …

We establish a cosmological-model-independent method to determine the Hubble constant
H 0 from the localized fast radio bursts (FRBs) and the Hubble parameter measurements …

Fast radio burst (FRB) is a type of extragalactic radio signal characterized by millisecond
duration, extremely high brightness temperature, and large dispersion measure. It remains a …

The cosmological 21 cm signal is one of the most promising avenues to study the Epoch of
Reionization. One class of experiments aiming to detect this signal is global signal …

Global 21-cm experiments are built to study the evolution of the Universe between the
cosmic dawn and the epoch of reionization. FlexKnot is a function parametrized by freely …

The dispersion of fast radio bursts (FRBs) is a measure of the large-scale electron
distribution. It enables measurements of cosmological parameters, especially of the …

The observed dispersion measures (DMs) of fast radio bursts (FRBs) are a good indicator of
the amount of ionized material along the propagation paths. In this work, we present a …

We investigate the three-dimensional clustering of sources emitting electromagnetic pulses
traveling through cold electron plasma, whose radial distance is inferred from their …
