论文摘要

最近的一项工作发现GRB及时通量,峰值通量(基于基于贝叶斯块的分析确定的最佳时间尺度)与使用Fermi Gamma-ray爆发监视器的数据之间存在紧密的全球关系,它们被称为“基本平面”。我们通过计算DEX中的散射来定量地表征这种基本平面关系的紧密度。我们还使用64毫秒,256 ms和1024 ms的时间尺度的峰值通量检查基本平面。为了进行分析,我们将不确定性纳入了上述可观察物,并同时进行了PCA和基于回归的分析。我们发现基本平面中的散射为0.16-0.17 dex。

A recent work has found a tight global relation between the GRB prompt fluence, peak flux (based on the optimum time scale determined from the Bayesian Blocks-based analysis) and duration using data from the Fermi Gamma-Ray burst monitor, which they have dubbed as "Fundamental Plane". We quantitatively characterize the tightness of this Fundamental Plane relation by calculating the scatter in dex. We also check for a fundamental plane using the peak flux over time scales of 64 ms, 256 ms and 1024 ms. For our analysis, we incorporate the uncertainties in the above observables and carried out both a PCA as well as regression-based analysis. We find that the scatter in the fundamental plane is 0.16-0.17 dex.
