论文摘要
詹姆斯·韦伯（James Webb）太空望远镜的推出将打开一个新的窗口，以最高的红移观察到Z〜15。但是，即使有了这个新的设施，第一批恒星仍将无法触及，因为它们出生于小型的灯光，即使是最长的曝光时间也无法检测到的灯光。在本文中，我们研究了最终大型望远镜的基本特性，该设施可以检测高红移的人口III星形成区域。观察将在近红外进行，因此提出了基于月球的设施。仪器需要达到淡淡的幅度，如39mag $ _ \ mathrm {ab} $，对应于直径约100m的主要镜像。假设使用JWST NiRcam过滤器，我们估计POP III来源将在颜色颜色的空间中具有独特的签名，并且可以明确识别。
The launch of the James Webb Space Telescope will open up a new window for observations at the highest redshifts, reaching out to z~15. However, even with this new facility, the first stars will remain out of reach, as they are born in small minihalos with luminosities too faint to be detected even by the longest exposure times. In this paper, we investigate the basic properties of the Ultimately Large Telescope, a facility that can detect Population III star formation regions at high redshift. Observations will take place in the near-infrared and therefore a moon-based facility is proposed. An instrument needs to reach magnitudes as faint as 39mag$_\mathrm{AB}$, corresponding to a primary mirror size of about 100m in diameter. Assuming JWST NIRCam filters, we estimate that Pop III sources will have unique signatures in a colour-colour space and can be identified unambiguously.
