This goal of this research program is to study the multifaceted problem of feedback via detailed simulations designed to model galactic star formation processes over a wide range of galaxy mass and size scales. The work will involve a series of high-resolution numerical simulations to investigate the detailed physics of feedback in disk galaxies by assessing the relative importance of supernova blasts, HII region expansion, streaming ultraviolet, and diffuse infrared emmision to driving turbulence in the ISM.Broader impacts of the work include training of undergraduate and graduate students, creation of ?visually rich? web pages, workshop coordination, and sharing of software with the community.

本研究计划的目标是通过详细的模拟来研究反馈的多方面问题，这些模拟旨在模拟在大范围的星系质量和大小尺度上的星系星星形成过程。 这项工作将涉及一系列高分辨率的数值模拟，以调查详细的物理反馈盘星系通过评估超新星爆炸，HII区域膨胀，流紫外线的相对重要性，并扩散红外发射驱动湍流的ISM。更广泛的影响，工作包括培训本科生和研究生，创建？视觉丰富？网页、研讨会协调以及与社区共享软件。
