Xu, Lixin 2010 检测伽马暴和超新星做标准烛光

主要内容:
用Amati关系,和超新星放一起,看他们是否一致。结论是基本一致的。不过他们貌似就5个暴,选择效应太大,再说Amati关系都不能做标准烛光的。

Abstract

In this paper, we test the consistence of Gamma Ray Bursts (GRBs) Data-set and Supernovae Union2 (SNU2) via the so-called {\it multi-dimensional consistence test} under the assumption that $\Lambda$CDM model is a potentially correct cosmological model. We find that the probes are inconsistent with $1.456\sigma$.
