Abstract

A spatially resolved JWST study of a quiescent massive galaxy and its neighbourhood at a high redshift reveals that just 1.6 Gyr after the Big Bang, the galaxy had formed $$\,{10}^{11}{M}_{\odot }$$ in stars and was surrounded by an abundant gas reservoir. Nevertheless, following early cessation of star formation, the galaxy remained quenched for more than 500 Myr.

一个早期熄灭的大质量星系及其邻近星系的地图

JWST对一个静止的大质量星系及其附近的高红移进行的空间分辨研究显示，在大爆炸后仅1.6 Gyr，该星系在恒星中形成$$\,{10}^{11}{M}_{\odot }$$，并被丰富的气藏包围。尽管如此，随着恒星形成的早期停止，星系仍然熄灭了500兆尔以上。

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
