Assembly and star formation activity of the Perseus galaxy cluster (Observing Campaign at the WIYN Telescope)

我们打算用WIYN望远镜的深紫外成像覆盖英仙座星系团的很大一部分。本项目的目标是：1）测量结构和颜色（恒星群体）的矮星系，特别侧重于确定恒星年龄和揭示最近的星星形成活动; 2）确定已经是星系团一部分的星系局部协会内的相互作用迹象; 3）将英仙座星系团的星系群与质量较小但同样集中的天炉座星系团进行比较，天炉座星系团目前正在进行深度成像。

We intend to cover a large part of the Perseus galaxy cluster with deep ultraviolet imaging at the WIYN telescope. The goals of this project are: 1) Measuring structure and colours (stellar populations) of dwarf galaxies, with a particular focus on determining stellar ages and revealing recent star formation activity; 2) Identifying signs of interactions within local associations of galaxies that are already part of the cluster; 3) Comparing the Perseus cluster's galaxy population with that of the less massive, but similarly concentrated Fornax cluster, which is currently being targeted with comparably deep imaging.
