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…
The energy conditions and model selection in the local Universe
Namit Chandak, Fulvio Melia, Junjie Wei
The four principal energy conditions (ECs) in general relativity prohibit negative energies, repulsive gravity and superluminal energy flows. One must invoke exotic matter to viola…
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…
Detecting Population III Gamma-Ray Bursts with Einstein Probe and Space-Based Multi-band Astronomical Variable Objects Monitor
Jun-Jie Wei, Qing-Bo Ma, Xue-Feng Wu
High-redshift gamma-ray bursts (GRBs), putative counterparts of massive, low-metallicity Population III (Pop III) stars, are a promising probe of the first stars. We assess the det…
