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…
A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…
Searching for Gamma Ray Bursts associated with CHIME Fast Radio bursts
Yi-Fang Liang, Ye Li, Bao Wang +3
Fast radio bursts (FRBs) and gamma-ray bursts (GRBs) are both linked to compact-object activity, yet their possible connection remains unclear. Here we perform a systematic search…
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…
