This project aims to discover the largest black holes in the early universe and their origin, and weigh them using infrared spectroscopy. Giant black holes at the centres of galaxies reach masses over ten billion times that of our Sun. Astronomy has revealed the origin of black holes with masses similar to that of the Sun, but remains puzzled by the existence of those with masses many million times larger. This project will reveal pathways of black-hole growth early after the Big Bang. The project will shed light on the evolution of galaxies in the early universe and prepare the ground for new work by other scientists, for example on the origin of the elements.

该项目旨在发现早期宇宙中最大的黑洞及其起源，并使用红外光谱对它们进行称重。星系中心的巨型黑洞质量达到太阳的100亿倍以上。天文学揭示了质量与太阳相似的黑洞的起源，但仍对质量大数百万倍的黑洞的存在感到困惑。这个项目将揭示大爆炸后早期黑洞成长的路径。该项目将阐明早期宇宙中星系的演化，并为其他科学家的新工作奠定基础，例如元素的起源。
