Model selection with the Pantheon+ Type Ia SN sample
Namit Chandak, Fulvio Melia, Junjie Wei
Recent discoveries, e.g., by JWST and DESI, have elevated the level of tension with inflationary CDM. For example, the empirical evidence now suggests that the standard model vi…
Model selection using the HII galaxy Hubble diagram
Jun-Jie Wei, Fulvio Melia
The proposal to use HII galaxies (HIIGx) and giant extragalactic HII regions (GEHR) as standard candles to construct the Hubble diagram at redshifts beyond the current reach of Typ…
New Tests on Lorentz Invariance Violation Using Energy-Resolved Polarimetry of Gamma-Ray Bursts
Jun-Jie Wei
One of the manifestations of Lorentz invariance violation (LIV) is vacuum birefringence, which leads to an energy-dependent rotation of the polarization plane of linearly polarized…
Constraining the Luminosity Function and Delay-Time Distribution of Short Gamma-Ray Bursts for Multimessenger Gravitational-Wave Detection Rate Estimation
Chong-Yu Gao, Jun-Jie Wei, Hou-Dun Zeng
In this work, we analyze the most recent short gamma-ray burst (sGRB) sample detected by the \emph{Fermi} satellite to reassess the sGRB luminosity function and formation rate. Usi…
Forecasts for Helium Reionization Detection with Fast Radio Bursts in the Era of Square Kilometre Array
Jun-Jie Wei, Chong-Yu Gao
The observed dispersion measures (DMs) of fast radio bursts (FRBs) are a good indicator of the amount of ionized material along the propagation paths. In this work, we present a fo…
Galaxy Ages with Redshift z=2-4: Stellar Population Synthesis for Candidates in FourStar Galaxy Evolution Survey
Chong-yu Gao, Martin Lopez-Corredoira, Jun-jie Wei
Observations of large amount of massive galaxies with relatively old populations found at high redshifts are challenging galaxy formation scenarios within standard cosmology. Preci…
Optimization of performance of the KM2A full array using the Crab Nebula
LHAASO collaboration
The full array of the Large High Altitude Air Shower Observatory (LHAASO) has been in operation since July 2021. For its kilometer-square array (KM2A), we have optimized the select…
Extragalactic Test of General Relativity from Strong Gravitational Lensing by using Artificial Neural Networks
Jing-Yu Ran, Jun-Jie Wei
This study aims to test the validity of general relativity (GR) on kiloparsec scales by employing a newly compiled galaxy-scale strong gravitational lensing (SGL) sample. We utiliz…
