摘要

事件视界望远镜(EHT)首次拍摄到超大质量黑洞的图像，揭示了椭圆星系M87和银河系中心的致密物体。提议通过下一代EHT (ngEHT)计划对该阵列进行升级，将大大提高现有EHT观测的角度分辨率、动态范围和时间覆盖范围。这些改进将独特地促成与黑洞科学相关的大量变革性新发现，从事件视界尺度的强引力研究到爆炸瞬变研究，再到超大质量黑洞的宇宙学增长和影响。在这里，我们提出了ngEHT的关键科学目标及其相关的仪器要求，这两个目标都是通过涉及全球数百名科学家的多年国际努力制定的。

Key Science Goals for the Next-Generation Event Horizon Telescope

The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way. Proposed upgrades to this array through the next-generation EHT (ngEHT) program would sharply improve the angular resolution, dynamic range, and temporal coverage of the existing EHT observations. These improvements will uniquely enable a wealth of transformative new discoveries related to black hole science, extending from event-horizon-scale studies of strong gravity to studies of explosive transients to the cosmological growth and influence of supermassive black holes. Here, we present the key science goals for the ngEHT and their associated instrument requirements, both of which have been formulated through a multi-year international effort involving hundreds of scientists worldwide.
