在2009年威尼斯会议上的一个讨论。文章貌似有所改动，分为 前身星、外流、暴本身和余辉四部分。
可以肯定的基本上只有相对论性的外流和余辉来自于外流与介质相互作用。

Abstract
Decades of improving data and extensive theoretical research have led to a popular model of gamma-ray bursts. According to this model, a catastrophic event in a stellar system results in the formation of a compact central engine, which releases a fraction of a solar rest-mass energy within seconds in the form of ultra-relativistic jets. Dissipation of the jets energy leads first to prompt gamma-ray emission and later to a long lasting afterglow. Here I summarize the introduction that I gave to the debate "where do we stand?" in the conference ``The Shocking Universe" held in Venice. This is a very brief summary of my view of the facts that we are (almost) certain about, models that are popular but may need rethinking, and main open questions.| Bibtex entry for this abstract Preferred format for this abstract (see Preferences) |
