摘要

形态学和动力学探讨早期星系形成。与先前的理解相反，早期星系由光滑结构组成，高分辨率观测结合引力透镜揭示了在大爆炸后9亿年的旋转星系中至少有15个恒星形成团块。这些观测结果挑战了目前关于早期星系形成的理论。

A young galaxy that consists of numerous star-forming clumps

Morphology and dynamics probe early galaxy formation. Contrary to previous understanding that early galaxies comprise smooth structures, high-resolution observations combined with gravitational lensing reveal at least 15 star-forming clumps within a rotating galaxy from 900 million years after the Big Bang. These observations challenge current theories of early galaxy formation.
