摘 要 用宇宙作为物理实验室,探索在地球上无法企及的条件下,例如极早期宇宙或黑洞视界附近强引力场中的物理规律,已成为新世纪物理学和天文学共同的前沿课题;空间天文观测是其中一个最重要的研究途径.自主研制和发放空间硬X射线调制望远镜(HXMT),实现中国空间天文卫星零的突破,是中国《“十一·五”空间科学发展规划》的目标之一. HXMT 将实现宽波段X射线 (1—250 keV) 巡天,其中在硬X射线波段具有世界最高灵敏度和空间分辨率,发现大批被尘埃遮挡的超大质量黑洞和未知类型天体,探测宇宙硬X射线背景辐射;HXMT还将通过对黑洞和其他高能天体宽波段X射线时变和能谱的观测,研究致密天体极端物理条件下的动力学和辐射过程. 基于成像技术创新提出HXMT项目迄今已有15年,能不能抓住技术创新所提供的科学机遇仍然是一个严重的挑战.

Abstract :Using the universe as a unique laboratory for probing the laws of physics in regimes not accessible on Earth, such as the very early universe or strong gravity fields near the event horizon of a black hole, is a new common frontier between physics and astronomy. The hard X-ray modulation telescope (HXMT) mission is the first dedicated astronomy satellite in the 2006—2010 five-year plan for space science unveiled by the National Space Administration of China. The HXMT mission will perform a wide band (1—250 keV) all-sky survey with the best sensitivity and angular resolution in the hard X-ray range as a black hole finder and cosmic hard X-ray background observer, and make sensitive pointed timing and spectral observations for studying the underlying physics processes of black holes and other compact objects. Fifteen years have passed since the submission of the HXMT proposal based on a new imaging technique. It is still a challenge for China to see if the scientific opportunity created by such a technological innovation can be finally grasped.
