太赫兹,一般定义为0.1THz~10THz的频率区间,对应的波长范围是3毫米至30微米,涵盖部分毫米波段、亚毫米波段和大部分远红外波段。太赫兹天文观测在恒星及其行星系统的形成与演化和早期宇宙演化等前沿领域研究中,具有不可替代的作用。超导探测器则在太赫兹谱段天体物理与宇宙学观测研究中发挥越来越重要的作用,推动了太赫兹天文学的快速发展。本报告将主要介绍当前国际主流的太赫兹高灵敏度超导探测技术发展现状和天文应用,并将介绍15米亚毫米波望远镜的前期推进工作。
THz is generally defined as the frequency range of 0.1THz~10THz, covering part of the millimeter, submillimeter and most of the far-infrared. THz astronomical observations play an important role in the research on the formation and evolution of stars and the evolution of the early universe. Superconducting detectors have promoted the rapid development of THz astronomy. This talk will introduce the superconducting detectors for terahertz astronomical applications and the preliminary work of the 15-meter submillimeter-wave telescope.
