长GRB脉冲的延迟、持续时间、峰值亮度、硬度和非对称性之间的相关性

Correlations between Lag, Duration, Peak Luminosity, Hardness, and Asymmetry in Long GRB Pulses

Jon Hakkila, Renata S. Cumbee

摘要:

BATSE目录的继续研究验证了先前确定的脉冲滞后和脉冲持续时间之间的相关性,以及大样本长GRB脉冲的两个属性和脉冲峰值通量之间的相应反相关性;研究还发现脉冲峰值滞后,脉冲不对称性和脉冲硬度之间的相关性。这些关系显然可以用来区分长伽玛暴和短伽玛暴。相关的脉冲属性表示的约束,可以用来指导理论建模,而批量提示发射性能似乎是通过组合和涂抹的方式,可能会失去有价值的信息的脉冲特性。

英文摘要:

Continued study of the BATSE catalog verifies previously-identified correlations between pulse lag and pulse duration and corresponding anti-correlations between both properties and pulse peak flux for a large sample of Long GRB pulses; the study also finds correlations between pulse peak lags, pulse asymmetry, and pulse hardness. These correlations apparently can be used to delineate Long GRBs from Short ones. Correlated pulse properties represent constraints that can be used to guide theoretical modeling, whereas bulk prompt emission properties appear to be constructed by combining and smearing out pulse characteristics in ways that potentially lose valuable information.
