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，我们写下了我们银河系的历史。在遥远的宇宙中观察到的大质量系统中，恒星紧密地聚集在比我们银河系圆盘小十倍的区域内。尽管它们似乎会随着时间的推移而消失，但我在遥远的地方发现了超致密星系，当时宇宙的年龄只有现在的三分之二。我将利用这些致密星系的相对邻近区域来绘制它们的亮物质和暗物质聚集体的演化路径(S)，并确定它们与我们所在星系的关系。
