Modeling the Distribution of Metals in the Universe

该项目旨在更好地了解重元素的运输。几乎所有比氢和氦重的元素都是在恒星中产生的，然后被驱逐到星际介质中。然而，我们对这些元素在星系中运输和运输出星系的后续过程知之甚少。该项目计划使用星际气体的高分辨率模拟来了解负责元素传输的流动。它还计划提供星际介质中元素扩散速率的定量计算，元素在星系风中从星系中排出的速率，以及类似的鲜为人知的量。最终，这项工作可能会对当今宇宙中元素的分布产生更深刻的理解。

This project aims to develop a better understanding of the transport of heavy elements. Almost all elements heavier than hydrogen and helium are made in stars and then expelled into the interstellar medium. However, we understand very little about the subsequent processes by which these elements are transported through and out of galaxies. This project plans to use high-resolution simulations of interstellar gas to understand the flows responsible for element transport. It also plans to provide quantitative calculations of the rate of element diffusion through the interstellar medium, the rate at which elements are expelled from galaxies in galactic winds, and similar poorly-known quantities. Ultimately, this work may yield a much deeper understanding of how the present-day distribution of elements in the universe came to be.
