原星系

A protogalaxy is a primordial cloud of gas and dust that will eventually collapse and form a galaxy.
一个原星系是最终会塌缩并形成星系的原始气体和尘埃云。
In the early universe, protogalaxies were the building blocks from which galaxies as we know them today assembled.
在早期宇宙中，原星系是我们今天所知的星系构建的基本单元。
Observations of protogalaxies provide insights into the conditions that prevailed during the formation of the first stars and galaxies.
对原星系的观测为我们揭示了在第一代恒星和星系形成时盛行的条件。
The gravitational interactions within protogalaxies lead to their eventual collapse and rotation, forming a disc-like structure.
原星系内部的引力相互作用导致其最终塌缩并旋转，从而形成了盘状结构。
Protogalaxies often contain large amounts of hydrogen and helium, with trace amounts of heavier elements produced by Population III stars.
原星系通常含有大量的氢和氦，以及由第三型早期恒星产生的痕量重元素。
Simulations of protogalaxy evolution help scientists understand how galaxies acquire their distinct shapes and sizes.
原星系演化的模拟帮助科学家理解星系是如何获得各自独特的形状和大小的。
Astronomers use radio telescopes to detect the faint emissions from protogalaxies at cosmic dawn, when the universe was only a few hundred million years old.
天文学家利用射电望远镜探测宇宙黎明时期，即宇宙仅有几亿年历史时原星系微弱的辐射发射。
Mergers between protogalaxies can result in the birth of massive elliptical galaxies or fuel the rapid growth of supermassive black holes at galactic centers.
原星系之间的合并可能导致质量极大的椭圆星系的诞生或加速位于星系中心的超大质量黑洞的增长。
Gravitational lensing allows us to observe distant protogalaxies that would otherwise be too faint to see with current telescope technology.
引力透镜效应使得我们能够观察到那些否则以现有望远镜技术而言过于暗淡而无法看见的遥远原星系。
Studying protogalaxies is crucial for understanding the processes that governed the cosmic structure formation and the hierarchical buildup of the universe.
研究原星系对于了解控制宇宙结构形成及宇宙层次化构建过程的关键机制至关重要。
