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…
Investigating the Anisotropy of Dispersion Measure Contribution from the Galactic Halo by Using Fast Radio Bursts
Yang Liu, Bao Wang, Puxun Wu +2
We propose a data-driven approach to reconstruct the all-sky distribution of the dispersion measure contribution from the Galactic halo () through a spherical h…
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…
Constraining the Baryon Fraction in Extragalactic Diffuse Ionized Gas with 124 Localized Fast Radio Bursts
Yang Liu, Yuchen Zhang, Jun-Jie Wei +3
Fast radio bursts (FRBs) are increasingly recognized as powerful cosmological tools for constraining the baryon fraction in extragalactic diffuse ionized gas, presenting a promisin…
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…
Alleviating the Hubble-constant tension and the growth tension via a transition of absolute magnitude favored by the Pantheon+ sample
Yang Liu, Hongwei Yu, Puxun Wu
We establish a cosmological-model-independent method to extract the apparent magnitude and its derivative at different redshifts from the Pantheon+ type Ia supernova sample, and fi…

Haixiang Zhang, Yang Liu, Hongwei Yu +3
In this paper, we use quasars calibrated from type Ia supernova (SN Ia) to constrain cosmological models. We consider three different X-ray luminosity () - ultraviolet lumin…
Observations favor the redshift-evolutionary - relation of quasars from copula
Bao Wang, Yang Liu, Hongwei Yu +1
We compare, with data from the quasars, the Hubble parameter measurements, and the Pantheon+ type Ia supernova, three different relations between X-ray luminosity () and ultra…
