A new measurement of the Hubble constant using fast radio bursts

Steffen Hagstotz et al.

Summary: We present the first measurement of the Hubble constant using fast radio bursts (FRBs), which can potentially resolve the tension between early and late-time measurements of H-0 in the near future.

CHIME/FRB Catalog 1 Results: Statistical Cross-correlations with Large-scale Structure

Masoud Rafiei-Ravandi et al.

Summary: The CHIME/FRB Project has released its first catalog of fast radio bursts (FRBs), which shows a statistically significant cross-correlation between CHIME FRBs and galaxies in the redshift range 0.3 ≤ z ≤ 0.5 in three photometric galaxy surveys: WISE x SCOS, DESI-BGS, and DESI-LRG. The results suggest that a fraction of CHIME FRBs may be located in the same dark matter halos as survey galaxies in this redshift range. Evidence is also found for a population of FRBs with large host dispersion measure, potentially related to gas in large halos.

Statistical modelling of the cosmological dispersion measure

Ryuichi Takahashi et al.

Summary: Through hydrodynamic simulations, the statistical properties of cosmological dispersion measure were studied, with analytical fitting functions provided for the free-electron power spectrum. By analyzing mock sky maps and source redshift distributions, the cosmological features of fast radio bursts were explored, expecting confirmation in future observations when more FRBs are available.

Revealing the cosmic reionization history with fast radio bursts in the era of Square Kilometre Array

Tetsuya Hashimoto et al.

Summary: This study introduces a method to directly measure the ionization fraction of the intergalactic medium using fast radio bursts, independent of the cosmic microwave background. By constructing mock FRB sources and reconstructing reionization histories, the study demonstrates the potential of future FRBs in constraining the reionization history.

The fast radio burst dispersion measure distribution

W. R. Arcus et al.

Summary: The study compared the dispersion measure statistics of FRBs detected by ASKAP and Parkes telescopes, finding similar patterns in their data. By modeling the DM distribution and fitting the population parameters, conclusions about the spectral index and burst energy distribution were drawn, revealing the impact of redshift evolutionary models on the parameters.

Exploring the epoch of hydrogen reionization using FRBs

Paz Beniamini et al.

Summary: This study introduces three methods for exploring the hydrogen reionization epoch using fast radio bursts (FRBs) and argues for the existence of FRBs at high redshift (z). The methods include determining the maximum dispersion measure (DMmax), measuring the redshifts of FRBs, and reflecting the reionization history in the number of FRBs per unit DM. These methods provide useful information about the reionization epoch without requiring extensive prior knowledge.

Reconstruction of reionization history through dispersion measurements of fast radio bursts

Ji-Ping Dai et al.

Summary: This paper investigates the evolution of ionization fraction during the epoch of reionization using dispersion measurements of fast radio bursts (FRBs). The study shows that the large-scale clustering information of observed FRB catalog is highly sensitive to the ionization fraction at the end of reionization epoch, providing significant improvement in constraining the width of the model compared to CMB data alone. The research suggests that high-redshift FRBs could serve as a complementary probe to study reionization history in the future.

Constraining the epoch of reionization with highly dispersed fast radio bursts

Michael Pagano et al.

Summary: The research considers using the mean dispersion measure of high redshift fast radio bursts as a probe of the underlying astrophysics and morphology of the epoch of reionization. The study finds that large samples of FRBs can constrain the duration and midpoint of reionization.

The cosmic dispersion measure in the EAGLE simulations

Adam J. Batten et al.

Summary: The dispersion measure of fast radio bursts can probe ionized baryons in the intergalactic medium, and using EAGLE simulations, it was found that a non-linear model with dependence on cosmological parameters provides a better fit to the DM-z relation. The differences between models are most significant at low redshifts.

Reionization effective likelihood from Planck 2018 data

Chen Heinrich et al.

Summary: RELIEK is a fast and accurate effective likelihood code based on Planck 2018 data, allowing constraints on reionization models between 6 < z < 30 with high consistency. Through testing on two example models, independent model-free constraints were derived for the total Thomson optical depth and high-redshift component.

Cobaya: code for Bayesian analysis of hierarchical physical models

Jesus Torrado et al.

Summary: Cobaya is a general-purpose Bayesian analysis code designed for models with complex internal interdependencies. It efficiently exploits interdependencies between different stages of a model pipeline, automatically caches intermediate results, and optimally sorts parameters to minimize computational costs during sampling. The code allows exploration of posteriors using Monte Carlo samplers, functions for maximization and importance-reweighting of samples, and can be extended and parallelized with minimal overhead per posterior evaluation.

Empirical estimates of the Galactic halo contribution to the dispersion measures of extragalactic fast radio bursts using X-ray absorption

Sanskriti Das et al.

Summary: This study presents an empirical list of Galactic dispersion measure contribution to extragalactic fast radio bursts along 72 sightlines, independent of any Galaxy models, with improved measurements compared to previous studies. DMGal does not show any trend with Galactic longitude or latitude, and there is a large scatter around predicted values by simple models.
