伽马射线暴的中央引擎余辉

Central engine afterglow of Gamma-ray Bursts

Yi-Zhong Fan, Tsvi Piran, Da-Ming Wei

摘要:

在2004年之前,几乎所有的伽玛暴余辉数据都可以在外部冲击模型的背景下理解。这种情况在过去两年中发生了变化,当时很明显,一些余辉成分应归因于中央发动机的活动;即,{ \it中央发动机余辉}。我们在这里审查余辉排放,是直接相关的伽玛射线暴中央引擎。Katz,Piran & Sari提出的这种解释在前{ \it Swift}时代是很独特的,现在已经被普遍接受。

英文摘要:

Before 2004, nearly all GRB afterglow data could be understood in the context of the external shocks model. This situation has changed in the past two years, when it became clear that some afterglow components should be attributed to the activity of the central engine; i.e., the {\it central engine afterglow}. We review here the afterglow emission that is directly related to the GRB central engine. Such an interpretation proposed by Katz, Piran & Sari, peculiar in pre-{\it Swift} era, has become generally accepted now.
