Tightening Bounds on Warm Dark Matter with High-Redshift Gamma-Ray Bursts
Jun-Jie Wei, Jing-Meng Hao, Ding-Fang Hu +4
The paper uses Swift gamma‑ray burst observations at redshifts up to 10 to place lower limits on the mass of warm dark matter particles, finding mₓ ≳ 1.3 keV (or ≳ 3.4 keV if the G…
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…
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…
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…
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…
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…
