摘要:

Cerro Chajnantor Atacama Telescope-prime(CCAT-prime)是一种新的6米,离轴,低发射率,大视场亚毫米望远镜,计划于2021年第四季度首次亮相。总之,(a)CCAT-prime独特地结合了大视场(高达8度),低发射率望远镜(< 2%)和出色的大气传输(5600米站点),以实现前所未有的亚毫米测量能力。(b)在五年的时间里,CCAT-prime第一代科学将解决恒星形成,星系演化和星系团形成的物理学问题;探测宇宙的再电离;改善对新粒子种类的约束;并提供改进的尘埃前景去除,以帮助寻找原始引力波。(c)天文台是由非联邦基金(私人和国际投资约4000万美元)建造的。仪器(约800万美元)和运营(每年1 - 200万美元)需要公共资金。作为回报,社区将能够参与调查规划并获得精选数据集。(d)对于第二代科学,CCAT-prime将具有独特的定位,与CMB-S4和/或西蒙斯天文台项目合作,为下一代CMB调查提供高频能力,或彻底改变宽场,亚毫米线强度测绘调查。

英文摘要:

The Cerro Chajnantor Atacama Telescope-prime (CCAT-prime) is a new 6-m, off-axis, low-emissivity, large field-of-view submillimeter telescope scheduled for first light in the last quarter of 2021. In summary, (a) CCAT-prime uniquely combines a large field-of-view (up to 8-deg), low emissivity telescope (< 2%) and excellent atmospheric transmission (5600-m site) to achieve unprecedented survey capability in the submillimeter. (b) Over five years, CCAT-prime first generation science will address the physics of star formation, galaxy evolution, and galaxy cluster formation; probe the re-ionization of the Universe; improve constraints on new particle species; and provide for improved removal of dust foregrounds to aid the search for primordial gravitational waves. (c) The Observatory is being built with non-federal funds (~ \$40M in private and international investments). Public funding is needed for instrumentation (~ \$8M) and operations (\$1-2M/yr). In return, the community will be able to participate in survey planning and gain access to curated data sets. (d) For second generation science, CCAT-prime will be uniquely positioned to contribute high-frequency capabilities to the next generation of CMB surveys in partnership with the CMB-S4 and/or the Simons Observatory projects or revolutionize wide-field, sub-millimetter line intensity mapping surveys.
