The observational and theoretical study of galaxy formation and evolution is one of the fields in astrophysics that will see tremendous progress in the next decade. A coherent picture of the physics involved drives the development of the next generation of instrumentation and demands adeptness with the latest sophisticated computational modeling techniques. The project outlined in this application describes a powerful adaptive multigrid code which includes self-gravity, hydrodynamics and star formation and will be employed for high-resolution cosmological simulations of galaxy formation and evolution. This non-proprietary code will be a unique contribution to the entire astronomical community's effort to understand the complicated physics of galaxy formation.

对星系形成和演化的观测和理论研究是未来十年天体物理学将取得巨大进展的领域之一。所涉及的物理学的连贯性图片驱动下一代仪器的发展，并要求熟练掌握最新的复杂的计算建模技术。在这个应用程序中概述的项目描述了一个强大的自适应多重网格代码，其中包括自引力，流体动力学和星星的形成，并将用于高分辨率的宇宙学模拟星系的形成和演化。这个非专有的代码将是对整个天文学界理解星系形成的复杂物理学的独特贡献。
