Measuring the Angular Auto-power Spectrum of Fast Radio Burst Dispersion Measures as a Robust Cosmological Probe and Baryon Tracer

Bao Wang, Zhiyu Lu, Yang Liu +2

Fluctuations in the cosmic electron density are imprinted on the dispersion measures (DMs) of fast radio bursts (FRBs), making DMs a promising probe of cosmology and the spatial di…

Tightening Bounds on Warm Dark Matter with High-Redshift Gamma-Ray Bursts

Jun-Jie Wei, Jing-Meng Hao, Ding-Fang Hu +4

The cold dark matter paradigm successfully explains large-scale structure but faces persistent tensions on small scales. Warm dark matter (WDM) with -scale particles…

Estimating Cosmological Parameters from Localized Fast Radio Bursts: A Method for Removing Milky Way Dispersion-Measure Contributions

Yuchen Zhang, Yang Liu, Hongwei Yu +1

Fast radio bursts (FRBs) are emerging as powerful probes for cosmology. However, cosmological inference based on FRB dispersion measures (DMs) is limited by uncertainties in the Mi…

Dispersion Measure Distribution of Unlocalized Fast Radio Bursts as a Probe of the Hubble Constant

Yang Liu, Jun-Jie Wei, Puxun Wu +1

We present constraints on the Hubble constant () derived from the observed dispersion measure (DM) distribution of unlocalized fast radio bursts (FRBs). While localized FRBs w…

Testing the Distance Duality Relation with Cosmological Observations at high Redshift using Artificial Neural Network

Yukang Xie, Yang Liu, Puxun Wu +2

The cosmic Distance Duality Relation (DDR) is a fundamental prediction of metric gravity under photon number conservation. In this work, we perform a model-independent test of the…

Photon rest mass from localized fast radio bursts with improved distribution of dispersion measure from extragalactic gas

Yuchen Zhang, Yang Liu, Hongwei Yu +1

The assumption that photons are massless is a foundational postulate of modern physics, yet it remains subject to experimental verification. Fast radio bursts (FRBs), with their co…

Revisiting the 150 MHz Radio Luminosity Function of Star-Forming Galaxies with LOFAR Deep Fields through a Refined Statistical Framework

Wenjie Wang, Zunli Yuan, Hongwei Yu +3

We present a comprehensive analysis of the 150~MHz radio luminosity function (LF) of star-forming galaxies (SFGs) using deep observations from the LOFAR Two-metre Sky Survey in the…

Probability density function for dispersion measure of fast radio burst from extragalactic medium

Yuchen Zhang, Yang Liu, Hongwei Yu +1

Fast Radio Bursts (FRBs) have emerged as powerful probes in cosmology. An optimized method was recently proposed to extract the cosmic baryon density from localized FRBs by maximiz…
