Cosmological Complexity from initial thermal state
Jincheng Wang, Hongwei Yu, Puxun Wu
The cosmological scalar perturbations should satisfy the thermal distribution at the beginning of inflation since the cosmic temperature is presumably very high. In this paper, we…
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…
Cosmological-model-independent determination of Hubble constant from fast radio bursts and Hubble parameter measurements
Yang Liu, Hongwei Yu, Puxun Wu
We establish a cosmological-model-independent method to determine the Hubble constant from the localized fast radio bursts (FRBs) and the Hubble parameter measurements from c…
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…
