Probing the Mass--Redshift Dependence of Binary Black Holes and its Implications for with GWTC-5.0
Yang Liu, Puxun Wu, Jun-Jie Wei +1
The mass and redshift distributions of merging binary black holes (BBHs) bear imprints of their astrophysical formation channels. Whether the BH mass distribution evolves with reds…
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…
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…
Measuring the Time Variation of the Fine-structure Constant with Quasars Detected by LAMOST
Jin-Nan Wei, Rui-Jie Chen, Jun-Jie Wei +2
The [O III] emission lines in the optical spectra of galaxies and quasars have been widely used to investigate the possible variation of the fine-structure constant…
Cosmology-independent Photon Mass Limits from Localized Fast Radio Bursts by using Artificial Neural Networks
Jing-Yu Ran, Bao Wang, Jun-Jie Wei
A hypothetical photon mass, , can produce a frequency-dependent vacuum dispersion of light, which leads to an additional time delay between photons with different frequencies…
