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…
GRID: a Student Project to Monitor the Transient Gamma-Ray Sky in the Multi-Messenger Astronomy Era
Jiaxing Wen, Xiangyun Long, Xutao Zheng +139
The Gamma-Ray Integrated Detectors (GRID) is a space mission concept dedicated to monitoring the transient gamma-ray sky in the energy range from 10 keV to 2 MeV using scintillatio…
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…
Polarization of Astrophysical Events with Precessing Jets
Mi-Xiang Lan, Rui Xue, Dingrong Xiong +3
A central compact object (CCO, e.g. a black hole) with an accretion disk has been suggested as the common central engine of various astrophysical phenomena, such as gamma-ray burst…
