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.

AST-9529328 Martin Weinberg 银河晕和盘中结构的激发和演化。 温伯格博士将研究具有活跃光晕的星系的动力学。 更具体地说，他将研究光晕中长寿命扰动模式的性质和激发、激发光晕对嵌入式圆盘的影响，以及圆盘中的长寿命模式及其对母体光晕的影响。 该研究将使用微扰理论和 N 体方法的紧密结合。 PI 计划在项目结束时向社区提供他的数字代码。
