Research on the redshift evolution of luminosity function and selection effect of GRBs
W. W. Tan, F. Y. Wang
We study the redshift evolution of the luminosity function (LF) and redshift selection effect of long gamma-ray bursts (LGRBs). The method is to fit the observed peak flux and reds…
The near-infrared radiation background, gravitational wave background and star formation rate of Pop III and Pop II during cosmic reionization
Y. P. Yang, F. Y. Wang, Z. G. Dai
In this paper, we obtain the NIRB and SBGWs from the early stars, which are constrained by the observation of reionization and star formation rate. We study the transition from Pop…
Cosmological test using strong gravitational lensing systems
C. C. Yuan, F. Y. Wang
As one of the probes of universe, strong gravitational lensing systems allow us to compare different cosmological models and constrain vital cosmological parameters. This purpose c…
An unexpectedly low-redshift excess of Swift gamma-ray burst rate
H. Yu, F. Y. Wang, Z. G. Dai +1
Gamma-ray bursts (GRBs) are the most violent explosions in the Universe and can be used to explore the properties of high-redshift universe. It is believed that the long GRBs are a…
Gamma-ray Burst Cosmology
F. Y. Wang, Z. G. Dai, E. W. Liang
Gamma-ray bursts (GRBs) are the most luminous electromagnetic explosions in the Universe, which emit up to erg isotropic equivalent energy in the hard X-ray band…
Constraining the bulk Lorentz factor from the photosphere emission
Yuan-Chuan Zou, K. S. Cheng, F. Y. Wang
We propose a direct and model-independent method to constrain the Lorentz factor of a relativistically expanding object, like gamma-ray bursts. Only the measurements, such as therm…
