伽马射线暴的费米观

The Fermi view of gamma-ray bursts

Frederic Piron, Valerie Connaughton

摘要:

自2008年6月成功发射以来,{ \it费米}伽玛射线空间望远镜在对伽马射线暴(GRB)现象的认识上取得了重要突破。{ \it Fermi}天文台上的GBM和LAT仪器的组合提供了70多年来对伽马射线暴能量观测的丰富信息。我们简要介绍了{ \it Fermi}仪器及其用于伽玛暴科学的能力,并报告了{ \it Fermi}对高能瞬发和扩展伽玛暴发射的观测结果。这些结果的主要物理意义进行了讨论,随着开放的问题,关于伽玛射线暴建模。我们强调未来在SVOM任务时与地面Čerenkov望远镜的协同作用。

英文摘要:

Since its successful launch in June 2008, the {\it Fermi} Gamma-ray Space Telescope has made important breakthroughs in the understanding of the Gamma-Ray Burst (GRB) phenomemon. The combination of the GBM and the LAT instruments onboard the {\it Fermi} observatory has provided a wealth of information from its observations of GRBs over seven decades in energy. We present brief descriptions of the {\it Fermi} instruments and their capabilities for GRB science, and report highlights from {\it Fermi} observations of high-energy prompt and extended GRB emission. The main physical implications of these results are discussed, along with open questions regarding GRB modelling. We emphasize future synergies with ground-based Čerenkov telescopes at the time of the SVOM mission.
