从伽马射线暴峰值光子能量和辐射热通量测量和其它数据对宇宙学参数的约束
Constraints on cosmological parameters from gamma-ray burst peak photon energy and bolometric fluence measurements and other data
摘要：
我们使用测量的峰值光子能量和辐射热通量的119伽马射线暴（GRB）的红移范围内的$0.3399 \leq z \leq 8.2$，同时确定宇宙学和Amati关系参数在六个不同的宇宙学模型。由此产生的阿马蒂关系参数是几乎相同的所有六个宇宙学模型，从而验证了使用阿马蒂关系标准化这些伽玛暴。伽玛射线暴数据宇宙学参数的限制是一致的，但显着较少的限制，从联合分析的重子声学振荡和哈勃参数测量。
英文摘要：
We use measurements of the peak photon energy and bolometric fluence of 119 gamma-ray bursts (GRBs) extending over the redshift range of $0.3399 \leq z \leq 8.2$ to simultaneously determine cosmological and Amati relation parameters in six different cosmological models. The resulting Amati relation parameters are almost identical in all six cosmological models, thus validating the use of the Amati relation in standardizing these GRBs. The GRB data cosmological parameter constraints are consistent with, but significantly less restrictive than, those obtained from a joint analysis of baryon acoustic oscillation and Hubble parameter measurements.
