中法SVOM伽玛暴研究计划

The Chinese-French SVOM mission for GRBs studies

Jacques Paul, Jianyan Wei, Stephane Basa, Shuang-Nan Zhang

摘要:

介绍了中国国家航天局和法国航天局决定联合实施的天基多波段天文可变天体监测器(SVOM)任务。SVOM被设计用于探测所有已知类型的伽马射线暴(GRB),提供快速可靠的GRB位置,测量GRB瞬发辐射的宽带光谱形状和时间特性,以及快速识别所探测GRB的光学/近红外余辉,包括高红移余辉。SVOM卫星计划在本十年的后五年进入轨道,它将携带一个非常创新的科学有效载荷,首次将一个用于伽马射线暴实时定位到几个弧分的宽视场X射线和伽马射线编码掩模成像仪、一个非成像伽马射线监测器和两个用于研究X射线和可见波段伽马射线暴早期余辉发射的窄视场仪器结合在一起。SVOM有效载荷由地面仪器补充,其中包括一台用于捕捉可见波段伽马射线暴瞬发辐射的宽视场照相机和两台用于测量早期余辉光度特性的机器人望远镜。特别关注伽玛射线暴的后续活动,以促进最大的地面望远镜对SVOM检测到的伽玛射线暴的观测。

英文摘要:

We present the SVOM (Space-based multi-band astronomical Variable Objects Monitor) mission that the Chinese National Space Agency and the French Space Agency have decided to jointly implement. SVOM has been designed to detect all known types of gamma-ray bursts (GRBs), to provide fast and reliable GRB positions, to measure the broadband spectral shape and temporal properties of the GRB prompt emission, and to quickly identify the optical/near-infrared afterglows of detected GRBs, including high-redshift ones. Scheduled to be in orbit in the second half of the present decade, the SVOM satellite will carry a very innovative scientific payload combining for the first time a wide field X- and gamma-ray coded mask imager for GRB real-time localizations to few arcmin, a non-imaging gamma-ray monitor, and two narrow-field instruments for the study of the GRB early afterglow emission in the X-ray and visible bands. The SVOM payload is complemented by ground-based instruments including a wide-field camera to catch the GRB prompt emission in the visible band and two robotic telescopes to measure the photometric properties of the early afterglow. A particular attention is paid to the GRB follow-up in facilitating the observation of the SVOM detected GRB by the largest ground based telescopes.
