研究人员分析了从星系核球——即银河系的中心区域——搜集的微重力透镜研究数据。
The researchers examined data collected from microlensing surveys of what is called the Galactic Bulge, the central area of our own Milky Way.
在每个星系的中心几乎都存在一个超大质量的黑洞，而这个黑洞的周围又包围着一个大核球。
At its center, nearly every large galaxy contains a supermassive black hole surrounded by a big bulge of stars.
一般，超大型黑洞出现在体积、质量更大，含有核球的星系中。
Normally, supermassive black holes are found in much larger, much more massive galaxies that have bulges.
至少螺旋星系的核球与晕，以及某些椭圆星系，可能是由此种碰撞产生的。
At least some elliptical galaxies, as well as the bulges and halos of spiral galaxies, may have arisen from such collisions.
天文学家为如何形成这些致密星系伤脑筋，也许它们最终成为大星系的致密核球区了。
Astronomers are puzzled by how galaxies like these formed. They may be what will eventually become the dense central regions of very large galaxies.
