Understanding how star clusters form and how their stellar feedback affects the surrounding interstellar medium is a key problem in Milky Way studies. We will quantify the physics of star formation and feedback using a combined numerical and observational approach, building a database of semi-analytical cluster feedback models and using it to make predictions for important observable quantities. We will use state-of-the-art 3-D simulations to benchmark our semi-analytical models. We will also apply a novel statistical method to Large Magellanic Cloud observations and compare the empirical timeline of star-forming regions with the predictions of our numerical models.

了解星星团如何形成以及它们的恒星反馈如何影响周围的星际介质是银河系研究中的一个关键问题。我们将量化的物理星星的形成和反馈使用相结合的数值和观测方法，建立一个数据库的半分析集群反馈模型，并使用它来预测重要的可观测量。我们将使用最先进的3D模拟来基准测试我们的半分析模型。我们还将应用一种新的统计方法来观测大麦哲伦星云，并将恒星形成区域的经验时间轴与我们的数值模型的预测进行比较。
