Model-independent Distance Calibration and Curvature Measurement using Quasars and Cosmic Chronometers
Jun-Jie Wei, Fulvio Melia
We present a new model-independent method to determine the spatial curvature and to mitigate the circularity problem affecting the use of quasars as distance indicators. The cosmic…
Constraining the Evolution of the Baryon Fraction in the IGM with FRB and H(z) data
Jun-Jie Wei, Zhengxiang Li, He Gao +1
Extragalactic dispersion measures (DMs) obtained from observations of fast radio bursts (FRBs) are an excellent tool for probing intergalactic medium (IGM) and for conducting cosmo…
The Luminosity Function and Formation Rate of A Complete Sample of Long Gamma-Ray Bursts
Guang-Xuan Lan, Hou-Dun Zeng, Jun-Jie Wei +1
We study the luminosity function and formation rate of long gamma-ray bursts (GRBs) by using a maximum likelihood method. This is the first time this method is applied to a well-de…
Limits on the Weak Equivalence Principle and Photon Mass with FRB 121102 Sub-pulses
Nan Xing, He Gao, Junjie Wei +5
Fast radio bursts (FRBs) are short duration (millisecond) radio transients with cosmological origin. The simple sharp features of the FRB signal have been utilized to probe t…
Precision Test of the Weak Equivalence Principle from Gamma-Ray Burst Polarization
Jun-Jie Wei, Xue-Feng Wu
If the weak equivalence principle (WEP) is broken, the measured values of the parametrized post-Newtonian parameter from photons with left- and right-handed circular polarizati…
New constraints on Lorentz invariance violation with polarized gamma-ray bursts
Jun-Jie Wei
Lorentz invariance violations (LIV) can yield vacuum birefringence, which results in an energy-dependent rotation of the polarization vector of linearly polarized emission from ast…
