三十米望远镜国际天文台(Thirty-Meter-Telescope International Observatory)

非盈利的TMT天文台公司成立于2003年6月。TMT源于三个较早的大型望远镜项目的合并,即加利福尼亚极大望远镜(CELT)、甚大光学望远镜(VLOT)和巨形拼接式镜面望远镜(GSMT)。
 
这些独立的项目目标近乎一致,即整合现今领先天文台运转经验,推动尖端技术的发展,拓展现有先进设施亦无法实现的天文学研究领域。
 
2003年,TMT召集了“科学顾问委员会”,成员包括其合作机构及更多科学界人士,来帮助TMT打造与下一代天文台需求相匹配的技术能力。
2014年5月6日,TMT国际天文台有限责任公司(TIO)成立,初始成员包括:

  • 美国加州理工学院
  • 日本国家自然科学研究所
  • 中国科学院国家天文台
  • 美国加州大学董事会 

         TIO负责TMT设计、开发、建造和运转。
2014年5月,加拿大大学天文学研究协会与印度天体物理学研究所作为合作机构加入,积极为TMT提供实物支持。另外,大学天文学研究协会也作为合作机构加入。
2014年12月,印度天体物理学研究所成为TMT国际天文台的正式成员。2015年4月,加拿大也作出相关承诺,并在2015年6月被选为全面合作伙伴。

TMT WFOS China Partnership Meeting

Beijing, China (October 16, 2017) – Representatives from the Thirty Meter Telescope’s (TMT’s) Wide-Field Optical Spectrograph (WFOS) team and TMT’s China partners gathered recently in China to discuss potential collaboration during the next stage of the conceptual design of WFOS.

 

WFOS is planned to be one of TMT’s first-light instruments. It will offer extraordinary new capabilities to study the early, distant universe, including the first stars and galaxies, and the intergalactic medium.

 

WFOS is now in its conceptual design phase, studying two different instrument designs: a slicer-based concept, and a fiber-based concept. The final decision will be made in March 2018. The next step will then include optimizing and prototyping the opto-mechanical design, fiber or slicer concepts, cameras, dispersive architecture, large refractive gratings, dichroics, robotics systems, and details of detector design. This will be followed by a two-year preliminary design phase, then final design, fabrication and integration and test phases, prior to fielding and commissioning on the telescope.

 

Dr. Fengchuan Liu, the Deputy Project Manager of TMT, updated the current status of TMT to all attendees remotely. WFOS Instrument Project Manager Maureen Savage (UCO), Lead Engineer Matthew Radovan (UCO) and Dr. Zheng Cai (UCO) introduced the program, the technical opportunities and the science goals of WFOS, respectively.

 

Representatives from several Institutes of Chinese Academy of Sciences and universities introduced their interests and their corresponding abilities, including National Astronomical Observatories of China (NAOC) and its affiliate, Nanjing Institute of Astronomical Optics & Technology (NIAOT); Shanghai Astronomical Observatory (SHAO); Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP); Shanghai Institute of Optics and Fine Mechanics (SIOM), University of Science and Technology of China (USTC); Shanghai Jiao Tong University (STJU); Huazhong University of Science and Technology (HUST); Beijing Institute of Technology (BIT).

 

The TMT WFOS delegation also visited SHAO, SIOM, NIAOT, USTC and Tsinghua University, and held face-to-face discussions with each team.

“使用巨型望远镜,照亮黑暗宇宙(Shedding Light on the Dark Universe with Extremely Large Telescopes)”国际研讨会在兰州召开

        8月30至9月2日,中科院近代物理研究所在兰州隆重召开“使用巨型望远镜,照亮黑暗宇宙(Shedding Light on the Dark Universe with Extremely Large Telescopes)”国际研讨会。本次会议是共计三期的系列研讨会(https://conferences.pa.ucla.edu/dark-universe/index.html)的开端。该系列研讨会的目的在于挖掘科学共同体的智慧以优化下一代巨型光学-红外望远镜的科学目标、科学运行和科学仪器计划。本次会议聚焦于下一代巨型望远镜将如何揭示暗物质和暗能量的本质问题。
        近代物理所Jarah Evslin研究员致欢迎辞并介绍了会议的背景和主题。 来自14个国家与地区的60余位天文学家齐聚一堂,对三大未来30米级光学-红外望远镜(Thirty Meter Telescope [TMT], Giant Magellan Telescope [GMT], and European Extremely Large Telescope [E-ELT])的科学目标、科学仪器和建设现状,以及它们与其它波段的下一代观测利器(如the Square Kilometre Array [SKA])的协同观测等问题进行了深入地探讨。
        中国是三十米望远镜(TMT)国际天文台的正式成员之一。TMT项目副经理刘凤川教授、TMT-中国项目科学家毛淑德教授以及TMT科学咨询委员会委员郝蕾研究员向与会者分别介绍了TMT的现状、建设计划和科学能力。毛淑德教授就“系外行星、地外生命和三十米望远镜”做了精彩的公众演讲。
        与会者就未来大望远镜时代如何利用不同的天体探针(星系团、超新星、近邻矮星系、强引力透镜和Lyman-alpha森林),结合大尺度巡天(如 eBOSS、PFS、LSST)来约束暗物质与暗能量的性质进行了热烈的讨论。深入的、富有针对性的理论和观测准备是未来光学巨镜能够充分发挥其科学潜力、做出重大科学发现的必要前提,本次会议为此做出了重要贡献。
