摘要:

由雨燕卫星首次探测到的伽马射线暴(GRB)的测量红移,似乎比其他卫星探测到的GRB的平均红移要大。我们分析了不同卫星(Swift[1],HETE 2 [2],BeppoSax,Ulysses)触发和观测到的伽玛暴的红移分布。在考虑可能的偏差后,HETE和Swift测量的伽玛暴红移分布在p = 95.70%水平上存在显著差异。

英文摘要:

The measured redshifts of gamma-ray bursts (GRBs), which were first detected by the Swift satellite, seem to be bigger on average than the redshifts of GRBs detected by other satellites. We analyzed the redshift distribution of GRBs triggered and observed by different satellites (Swift[1], HETE2[2], BeppoSax, Ulyssses). After considering the possible biases significant difference was found at the p = 95.70% level in the redshift distributions of GRBs measured by HETE and the Swift.
