Excitation and Evolution of Structure in Galactic Halos and Disks

9529328马丁温伯格激发和银晕和银盘结构的演化。温伯格博士将研究有活动晕的星系的动力学。更具体地说，他将研究晕中长寿命微扰模的性质和激发，激发晕对嵌入盘的影响，以及盘中的长寿命模及其对母晕的影响。这项研究将使用微扰理论和N体方法的紧密结合。PI计划在项目结束时将他的数字代码提供给社区。

AST-9529328 Martin Weinberg Excitation and Evolution of Structure in Galactic Halos and Disks. Dr. Weinberg will study the dynamics of galaxies with active halos. More specifically he will examine the nature and excitation of long-lived perturbation modes in halos, the influence of an excited halo on an embedded disk, and long-lived modes in disks and their effects on parent halos. The research will use a closely coupled combination of perturbation theory and N-body methods. The PI plans to make his numerical codes available to the community at theend of the project.
