作为强磁场源的伽马射线暴

Gamma-Ray Bursts as Sources of Strong Magnetic Fields

Jonathan Granot, Tsvi Piran, Omer Bromberg, Judith L. Racusin, Frédéric Daigne

摘要:

伽马射线暴(GRB)是宇宙中最强的爆炸,由于其极端的性质,可能涉及自然界中最强的磁场。本文综述了磁场在伽玛暴中的可能作用,从伽玛暴的中心引擎,通过其超相对论喷流的发射、加速和准直,到为伽玛暴的$γ$射线发射提供动力的耗散和粒子加速,以及伽玛暴驱动到周围介质中产生长寿命余辉发射的强大冲击波。重点放在近年来有令人感兴趣的发展的特定领域。

英文摘要:

Gamma-Ray Bursts (GRBs) are the strongest explosions in the Universe, which due to their extreme character likely involve some of the strongest magnetic fields in nature. This review discusses the possible roles of magnetic fields in GRBs, from their central engines, through the launching, acceleration and collimation of their ultra-relativistic jets, to the dissipation and particle acceleration that power their $γ$-ray emission, and the powerful blast wave they drive into the surrounding medium that generates their long-lived afterglow emission. An emphasis is put on particular areas in which there have been interesting developments in recent years.
