Collaborative Project: The Structure and Origin of the Galactic Halo

AST-9619490亚利桑那大学的Edward Olszewski博士、密歇根大学的Mario Mateo博士和凯斯西部储备大学的Heather Morison博士将实施一项合作项目，绘制银河系外晕的地图，以搜索可能是银河系吸积小星系的残骸的可能移动的恒星群。其目的是通过确定晕的含量来更清楚地了解我们银河系的合并历史，这些晕可以归因于附近相互作用的小星系的吸积。这是一个非常雄心勃勃的观测项目，将在南北半球的望远镜上进行。

AST-9619490 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.
