How the Interstellar Medium Moves: Testing Simulations

9721455 Alyssa Goodman博士将开展一个项目，对恒星之间的物质(即星际介质)如何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上的差距。该项目完成后，应向天文学团体提供一套优化的物理驱动的统计诊断方法，最好地捕捉星际物质的三维地图的性质，无论是模拟的还是观测的。这样的统计诊断将成为对我们银河系中恒星形成区域、超新星遗迹、大型星系云和扩散云的物理性质的宝贵探测。***

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. ***
