Calibrating Gamma-Ray Bursts by Using a Gaussian Process with Type Ia Supernovae
Nan Liang, Zihao Li, Xiaoyao Xie +1
In this paper, we calibrate the Amati relation (the - correlation) of gamma-ray bursts (GRBs) in a cosmology-independent way. By using Gaussian process to…
Redshift-evolutionary X-ray and UV luminosity relation of quasars from Gaussian copula
Bao Wang, Yang Liu, Zunli Yuan +3
We construct a three-dimensional and redshift-evolutionary X-ray and ultraviolet () luminosity relation for quasars from the powerful statistic tool called copula, and…
Gamma ray burst constraints on cosmological models from the improved Amati correlation
Yang Liu, Nan Liang, Xiaoyao Xie +3
An improved Amati correlation was constructed in (ApJ 931 (2022) 50) by us recently. In this paper, we further study constraints on the CDM and CDM models from the gamma ray…
The improved Amati correlations from Gaussian copula
Yang Liu, Fuyong Chen, Nan Liang +3
In this paper, we obtain two improved Amati correlations of the Gamma-Ray burst (GRB) data via a powerful statistical tool called copula. After calibrating, with the low-redshift G…
