How does the interstellar medium (ISM) evolve in the Milky Way, and how does atomic gas convert into molecular clouds? How do global dynamics influence the ISM, and what drives the formation of filaments on all spatial scales? We will address these questions from a theoretical as well as observational perspective. Using the moving-mesh code Arepo, we will perform global simulations of the Galactic ISM including time-dependent chemistry as well as all forms of stellar feedback. On the observational side, we will combine atomic and molecular gas data to study the formation of large-scale molecular clouds and the transformation of the atomic to the molecular phase.

星际介质（ISM）在银河系中是如何演化的，原子气体是如何转化为分子云的？全球动力学如何影响ISM，是什么驱动了所有空间尺度上细丝的形成？我们将从理论和观察的角度来解决这些问题。使用移动网格代码Arepo，我们将执行银河ISM的全球模拟，包括时间依赖的化学以及所有形式的恒星反馈。在观测方面，我们将结合联合收割机原子和分子气体数据，研究大规模分子云的形成以及原子相到分子相的转变。
