AST-9619524 Dr. Edward Olszewski, at the University of Arizona, Dr. Mario Mateo, at the University of Michigan, and Dr. Heather Morrison, at Case Western Reserve University will carry out a collaborative project to map the outer halo of the Milky Way to search for possible moving groups of stars which are likely remnants of accretion of smaller galaxies by the Milky Way. The goal is to obtain a clearer understanding of the merger history of our Galaxy, by determining the content of the halo that can be attributed to accretion from small, nearby, interacting galaxies. This is a very ambitious observational project that will be carried out on telescopes in both the northern and southern hemispheres.

亚利桑那大学的Edward Olszewski博士、密歇根大学的Mario Mateo博士和凯斯西储大学的Heather Morrison博士将进行一项合作项目，绘制银河系外晕的地图，以寻找可能的移动恒星群，这些恒星群可能是银河系中较小星系吸积的残留物。目标是通过确定光环的内容来更清楚地了解我们银河系的合并历史，这些光环可以归因于附近的小型相互作用星系的吸积。这是一个非常雄心勃勃的观测项目，将在北半球和南半球的望远镜上进行。
