The mysterious thick disk: Unifying Galactic and extragalactic dynamics

银河系古老的厚盘的起源目前还没有任何简单的解释。该项目旨在解决这一问题，并将直接挑战现有的磁盘形成模型。回答这个问题的新的创新方法将是同时测量附近银河系类似物的化学和动力学特性。通过统一银河系和星系外动力学的观点，该项目寻求提供关于厚盘形成的新理解。预期的结果包括，关于盘状星系形成的强有力的新证据，发现大量动态的银河系类似物，并从宇宙学模拟中建立最合理的银河系形成途径。

The origin of the Milky Way’s ancient thick disk currently defies any easy explanation. This project aims to resolve this problem and will directly challenge existing models of disk formation. The new innovative approach to answering this question will be to simultaneously measure both the chemical and dynamical properties of nearby Milky Way analogues. By unifying the perspectives of Galactic and extragalactic dynamics the project seeks to deliver new understandings about thick disk formation. Expected outcomes include, robust new evidence about disk galaxy formation, discovery of a large number of dynamical Milky Way analogues, and establishing the most plausible Milky Way formation pathway from cosmological simulations.
