Groups and clusters of galaxies are truly remarkable structures. With masses equivalent to anywhere from 10,000 billion suns to a mind-boggling million billion suns, these systems are the largest, most massive gravitationally bound objects in the Universe. Moreover, having formed relatively recently, these systems still bear the imprints of the processes that led to their formation. Studying these cosmic colossi, therefore, offers a unique window into the very processes that have shaped cosmic structure formation.

星系群和星系团是真正非凡的结构。 这些系统的质量相当于10万亿个太阳到令人难以置信的100亿个太阳，是宇宙中最大、最大的引力束缚物体。 此外，这些制度形成的时间较晚，仍然带有导致其形成的过程的印记。 因此，研究这些宇宙结构提供了一个独特的窗口，可以了解塑造宇宙结构形成的过程。
