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.

通过追踪宇宙时间中星系的多样性，我们写下了我们自己星系的历史。在遥远宇宙中观测到的大质量系统中，恒星紧密地聚集在比我们银河系圆盘小十倍的区域内。虽然它们似乎会随着时间的推移而消失，但我在宇宙年龄为目前年龄的三分之二时发现了超紧凑星系。我将利用这些致密系统的相对邻近性来绘制它们的发光和暗物质聚集体的演化路径，并确定它们与像我们这样的星系的关系。
