伽马射线暴的差分源计数

Differential Source Count for Gamma Ray Bursts

Shreya Banerjee, David Eichler, Dafne Guetta

摘要:

本文在一个显式物理模型的基础上讨论了不同形式的长伽马射线暴(GRB)的光度函数。我们还将推测的通量分布与观测到的两个样本GRB,Swift和Fermi GBM的通量分布进行了比较。找到了光度函数的最佳拟合参数,并讨论了其物理解释。结果与观测到的相当数量的平坦相位余辉和单调递减余辉相一致。

英文摘要:

Different forms of long gamma-ray bursts (GRBs) Luminosity Functions are considered on the basis of an explicit physical model. The inferred flux distributions are compared with the observed ones from two samples of GRBs, Swift and Fermi GBM. The best fit parameters of the Luminosity functions are found and the physical interpretations are discussed. The results are consistent with the observation of a comparable number of flat phase afterglows and monotonic decreasing ones.
