XRT光变曲线的10年:X射线余辉的一般看法

10 Years of XRT light curves: a general view of the X-ray afterglow

O. Bardho, M. Boer, B. Gendre

摘要:

在雨燕前时期,在伽马射线暴的X射线、光学和红外余辉中观察到了一组光变曲线。我们使用了254个伽玛射线暴X射线余辉的样本来验证斯威夫特时代的这一事实。我们校正了距离、时间膨胀和宇宙学效应造成的能量损失的通量。我们所有的数据都在手中,我们面临一个问题:我们的数据分散。我们研究了3种可能性来解释这一点,即:聚类不存在,数据校准过程中存在问题,以及存在仪器问题。我们最终确认我们的样本与Dainotti相关性是一致的。

英文摘要:

During the pre-Swift era, a clustering of light curves was observed in the X-ray, optical and infrared afterglow of gamma-ray bursts. We used a sample of 254 GRB X-ray afterglows to check this fact in the Swift era. We corrected fluxes for distance, time dilation and losses of energy due to cosmological effects. With all our data in hand, we faced with a problem: our data were scattered. We investigated 3 possibilities to explain this, namely: the clustering does not exist, there are problems during calibration of data, and there are instrumental problems. We finally confirm that our sample is consistent with Dainotti correlation.
