摘要:

超过红移$\sim6$的高红移伽马射线暴(GRB)是探测遥远的早期宇宙的潜在有力工具。要在真正的高红移下大量探测到它们,就需要下一代高能宽场仪器,其灵敏度要比目前轨道上的仪器高出至少一个数量级。另一方面,对高红移伽玛暴的余辉进行后续观测并识别其宿主星系,这对于目前正在运行的望远镜来说是困难的,需要新的,非常大的多波长设施。本章介绍了未来的实验,预计将推进这一令人兴奋的领域,目前正在建设和正在提出。Swift的遗产将由SVOM继续,SVOM配备了一套天基多波长仪器以及地面部分,包括一个广角相机和两个后续望远镜。已经建立的龙虾眼X射线聚焦光学系统为探测非常远距离的微弱伽玛暴提供了一种有前途的技术,在此基础上,提出了THESEUS、Einstein Probe和其他任务概念。利用射电望远镜{SKA}、光学/近红外30米级望远镜、光学/近红外/中红外星载望远镜{WFIRST}和{JWST}等大型设备,对再电离时代进行后续观测和探索,并介绍X射线和$γ$射线偏振实验POLAR。

英文摘要:

High-redshift Gamma-Ray Bursts (GRBs) beyond redshift $\sim6$ are potentially powerful tools to probe the distant early Universe. Their detections in large numbers and at truly high redshifts call for the next generation of high-energy wide-field instruments with unprecedented sensitivity at least one order of magnitude higher than the ones currently in orbit. On the other hand, follow-up observations of the afterglows of high-redshift GRBs and identification of their host galaxies, which would be difficult for the currently operating telescopes, require new, extremely large facilities of at multi-wavelengths. This chapter describes future experiments that are expected to advance this exciting field, both being currently built and being proposed. The legacy of Swift will be continued by SVOM, which is equipped with a set of space-based multi-wavelength instruments as well as and a ground segment including a wide angle camera and two follow-up telescopes. The established Lobster-eye X-ray focusing optics provides a promising technology for the detection of faint GRBs at very large distances, based on which the {THESEUS}, {Einstein Probe} and other mission concepts have been proposed. Follow-up observations and exploration of the reionization era will be enabled by large facilities such as {SKA} in the radio, the 30m class telescopes in the optical/near-IR, and the space-borne {WFIRST} and {JWST} in the optical/near-IR/mid-IR. In addition, the X-ray and $γ$-ray polarization experiment POLAR is also introduced.
