How is the Central Molecular Zone (CMZ) of the Milky Way supplied with gas, and how does this influence the rate at which stars form there? We will address these questions with a combination of numerical simulations and observations. We will simulate the inflow of gas along the stellar bar and onto the CMZ and will use these simulations to make detailed predictions for the star formation rate as a function of time and of location within the CMZ. We will also study the assembly history of the Galactic Center region by using large-area near-infrared spectroscopic surveys to identify young stars, enabling us to quantify the current star formation rate throughout the CMZ.

银河系的中央分子带（CMZ）是如何被提供气体的，这又是如何影响那里恒星形成的速度的？我们将结合数值模拟和观测来解决这些问题。我们将模拟气体沿着恒星棒流入CMZ，并将使用这些模拟来详细预测星星形成率作为时间和CMZ内位置的函数。我们还将通过使用大面积近红外光谱测量来识别年轻恒星，从而研究银河系中心区域的组装历史，使我们能够量化整个CMZ当前的星星形成率。
