论文摘要
在过去的两年中，人们普遍接受了这一想法，即银河系在很大程度上是在早期（8-10 Gyr）和大量（$> 10^{10} m_ \ odot $）合并中创建的。这一想法的根源是盖亚（Gaia）的任务，但盖亚（Gaia）提供的精致适当动议使该假设无法抗拒。我们追踪了这个想法的历史，回顾了导致我们当前理解的一系列论文。
The last two years have seen widespread acceptance of the idea that the Milky Way halo was largely created in an early (8-10 Gyr ago) and massive ($> 10^{10} M_\odot$) merger. The roots of this idea pre-date the Gaia mission, but the exquisite proper motions available from Gaia have made the hypothesis irresistible. We trace the history of this idea, reviewing the series of papers that led to our current understanding.
