| 摘 要： | 我们选取76个红移已知Swift伽玛暴(含有61个长暴和15个短暴),分析了各向同性能量,光度和峰值能量之间的相关性,研究发现Swift长暴存在Amati关系,而短暴存在Ghirlanda关系和Amati关系。我们还发现了Swift/BAT长暴和短暴的Ep.i-Lp关系都分别存在且是一致的,并且符合Zhang,DaiHuang之前利用多个卫星数据得到的结果。

| Abstract: | The correlations between peak energy, isotropic energy and isotropic luminosity were investigated based on the data of 76 Swift gamma-ray bursts including 61 long and 15 short bursts with known redshifts. Our analysises show that the so-called Amati relation exists for the Swift long bursts, while the Amati relation and the Ghirlanda relation are existent for the short bursts. We also find that the Ep. i - Lp correlation is unified between the Swift/BAT long and short bursts. Furthermore, it is found that the Ep. i - Lp correlation is consistent with that of Zhang, Dai ＆ Huang derived from Multiple satellites. |
