解开黑暗时代任务的高z伽马射线暴HiZ-GUNDAM
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
摘要：
我们目前正在调查和研究一个小型卫星任务HiZ-GUNDAM，用于今后观测伽马射线暴。任务概念是探测“黑暗时代的结束和天体形成的曙光”，即红移z > 7以外的早期宇宙的物理条件。我们将考虑两种类型的任务有效载荷，（1）用于发现GRB的宽视场X射线成像探测器，以及（2）直径为30 cm的近红外望远镜，以有效地选择高z GRB候选者。本文根据以往的观测资料，阐述了推进伽玛暴宇宙学研究的一些必要条件，介绍了HiZ-GUNDAM的任务概念和X射线成像探测器的基本进展。
英文摘要：
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages and the dawn of formation of astronomical objects", i.e. the physical condition of early universe beyond the redshift z > 7. We will consider two kinds of mission payloads, (1) wide field X-ray imaging detectors for GRB discovery, and (2) a near infrared telescope with 30 cm in diameter to select the high-z GRB candidates effectively. In this paper, we explain some requirements to promote the GRB cosmology based on the past observations, and also introduce the mission concept of HiZ-GUNDAM and basic development of X-ray imaging detectors.
