AI总结:

利用AtLAST升级EHT,通过提升灵敏度和多频段能力,扩展对黑洞视界尺度源的观测,研究黑洞生长、吸积物理及喷流发射。

摘要:

事件视界望远镜(EHT)已直接解析并成像了两个超大质量黑洞,为黑洞物理打开了新的窗口。然而,当前的阵列仅限于这两个最明亮的近邻目标。本文白皮书概述了未来EHT升级方案,以阿塔卡马大孔径毫米波望远镜(AtLAST)为核心,将使可访问的视界尺度源群体发生变革性扩展。通过显著提高灵敏度和多频段能力,EHT+AtLAST将使黑洞增长、吸积物理和喷流发射在广泛的质量和环境以及吸积状态下的群体研究成为可能。

英文摘要:

The Event Horizon Telescope (EHT) has directly resolved and imaged two supermassive black holes and opening a new window on black hole physics. However, the current array is limited to only these two brightest nearby targets. This white paper outlines how future EHT upgrades, anchored by the Atacama Large Aperture Submillimeter Telescope (AtLAST), will enable a transformative expansion of the accessible population of event-horizon-scale sources. By substantially improving sensitivity and multi-frequency capabilities, EHT+AtLAST will enable demographic studies of black hole growth, accretion physics, and jet launching across a wide range of masses, environments, and accretion states.
