By tracing the diversity of galaxies through cosmic time we write the history of our own Galaxy. In massive systems observed in distant universe stars are tightly packed within regions ten times smaller than our Galaxy's disk. Although they seemed to disappear with time, I discovered ultra-compact galaxies at distances when the universe was two-thirds its current age. I will use relative vicinity of these dense systems to map the evolutionary path(s) of their luminous and dark matter aggregates and to determine their relation to galaxies like our own.

通过在宇宙时期追踪星系的多样性，我们写下了自己的星系历史。在遥远的宇宙中观察到的大型系统中，恒星在区域内紧密堆积了十倍，比我们的银河磁盘小十倍。尽管它们似乎随着时间的流逝而消失，但我在宇宙的当前年龄三分之二时发现了超紧凑的星系。我将使用这些密集系统的相对附近来绘制其发光和暗物质聚集体的进化路径，并确定它们与我们自己的星系的关系。
