Simulating the Turbulent, Multiphase Interstellar Medium: Comparing with Observations

由于它在现代天体物理学的许多方面的作用，从恒星形成到年轻和年老星系的演化，理解星际介质（ISM）的物理学是至关重要的。由于最近的地面和天基观测，提高对ISM热相和暖相以及ISM湍流混合的理论认识是很重要的。这个项目将通过数值模拟来解决这些需求，现在现代系统已经足够快地模拟星系中ISM的各个部分。在许多情况下，一个输出将是模拟诊断，以便与观测结果进行直接比较。这项工作将提供研究生论文、本科生研究培训、面向学校的网站，并为将科学带入K-12教室的“艺术到科学”计划做出贡献。

AST-0607731BalsaraDue to its role in numerous aspects of modern astrophysics, from star formation to the evolution of both young and old galaxies, understanding the physics of the interstellar medium (ISM) is of fundamental importance. Because of recent ground- and space-based observations, it is important to improve theoretical understanding of the hot and warm phases of the ISM, and of turbulent mixing in the ISM. This project will address these needs with numerical modeling, now that modern systems are fast enough simulate sections of the ISM in a galaxy. In many cases, one output will be simulated diagnostics for direct comparison with the observations.The work will provide for a graduate thesis, undergraduate research training, school-targeted web sites, and a contribution to the 'Art to Science' program that takes science into K-12 classrooms.
