How the Interstellar Medium Moves: Testing Simulations

[9721455]阿莉莎·古德曼博士将开展一个项目，为恒星之间的物质（即星际介质）的分布提供新的定量测量方法。她将开发新的定量方法来分析数值模拟和观测数据集，并使用这些方法来弥合我们对数值模拟和星际介质之间关系的理解差距。完成后，该项目将为天文学界提供一套优化的物理驱动统计诊断，最好地捕捉星际物质三维地图的属性，无论是模拟的还是观察到的。这样的统计诊断将成为我们银河系中恒星形成区域、超新星遗迹、大星系云和弥散云的物理特性的宝贵探测。＊＊＊

9721455 Alyssa Goodman Dr. Alyssa Goodman will carry out a project that will offer quantitative new measures of how the material between the stars, known as the interstellar medium, is distributed. She will develop new quantitative methods for analyzing both numerical simulations and observed data sets, and to use these methods to bridge the gap in our understanding of the relationship between numerical simulations and the interstellar medium. Upon completion, the project should provide the astronomical community with an optimized set of physically-motivated statistical diagnostics that best capture the properties of a three-dimensional map of interstellar material, either simulated or observed. Such statistical diagnostics will become invaluable probes of the physical properties of star forming regions, supernova remnants, large galactic clouds, and diffuse clouds in our Galaxy. ***
