Cuesta 2007 伽玛暴在Gurzadyan-Xue的宇宙学模型中的应用

主要内容:
Gurzadyan-Xue宇宙模型号称是不依赖于自由参数的，就是和标准的Friedman模型依赖于哈勃常数对比吧。（没看懂他们的模型）

作者就是把Gurzadyan-Xue模型给出的光度距离D_L和观测对比定宇宙学参数。认为伽玛暴还是可以定宇宙学参数的。

Gamma-ray bursts being the most luminous among known cosmic objects carry an essential potential for cosmological studies if properly used as standard candles. This appears to be possible due to the use of several empirical relations obtained for gamma-ray burst (GRBs) observables which, after a consistent calibration for a specific model, enables one to probe current cosmological models. In this paper we test the Gurzadyan-Xue cosmological models of dark energy and show their compatibility to the GRBs observational data. The analysis supports the view that GRBs contain more decisive information about cosmological models and parameters than supernovas, mainly because of the huge increase in the traced cosmic distance scale.
