Tightening Cosmological Constraints Within and Beyond CDM Using Gamma-Ray Bursts Calibrated with Type Ia Supernovae

Wei Hong, Luca Izzo, Massimo Della Valle +3

Context. Gamma-ray bursts (GRBs) reach redshifts beyond Type Ia supernovae (SNe Ia) and can extend distance measurements into the early Universe, but their use as distance indicato…

High Sensitivity Methodologies to Detect Radio Band Gravitational Waves

Wei Hong, Peng He, Tong-Jie Zhang +2

Gravitational waves (GWs) can resonate with magnetic fields through the Gertsenshtein-Zeldovich effect, producing electromagnetic signals at the same frequency. In pulsar magnetosp…

Polarization Properties of the Electromagnetic Response to High-frequency Gravitational Wave

Jian-Kang Li, Wei Hong, Tong-Jie Zhang

Electromagnetic waves (EMWs) can be generated by gravitational waves (GWs) within a magnetic field via the Gertsenshtein effect. The conversion probability between GWs and EMWs can…

Theoretical Radio Signals from Radio-Band Gravitational Waves Converted from the Neutron Star Magnetic Field

Wei Hong, Zhen-Zhao Tao, Peng He +1

Gravitational waves (GWs) can convert into electromagnetic waves in the presence of a magnetic field via the Gertsenshtein-Zeldovich (GZ) effect. The characteristics of the magneti…

Cosmic Dynamics in Einstein-Cartan Theory: Analysing Hubble Tension through Curvature and Torsion field

Yun-Dong Wu, Wei Hong, Tong-Jie Zhang

The Hubble tension refers to the significant discrepancy in the Hubble constant obtained from two different measurement methods in cosmology. One method derives data from t…

A Stochastic Approach to Reconstructing the Speed of Light in Cosmology

Cheng-Yu Zhang, Wei Hong, Yu-Chen Wang +1

The Varying Speed of Light (VSL) model describes how the speed of light in a vacuum changes with cosmological redshift. Despite numerous models, there is little observational evide…

Effect of Neutrinos on Angular Momentum of Dark Matter Halo

Yu Chen, Chang-Zhi Lu, Yu Lu +2

Massive neutrinos are expected to affect the large-scale structure formation, including the major component of solid substances, dark matter halos. How halos are influenced by neut…

Likelihood-free Cosmological Constraints with Artificial Neural Networks: An Application on Hubble Parameters and SNe Ia

Yu-Chen Wang, Yuan-Bo Xie, Tong-Jie Zhang +3

The errors of cosmological data generated from complex processes, such as the observational Hubble parameter data (OHD) and the Type Ia supernova (SN Ia) data, cannot be accurately…
