The group environment: a key to galaxy evolution and quasar activity

附近质量最大的星系在宇宙当前年龄的四分之一到一半的时候建立了它们的大部分恒星和中心的超大质量黑洞。这些过程的同时代时间，以及黑洞质量和它们的宿主星系之间明显固定的关系，表明了这两个现象之间的联系。我提出的研究计划通过关注黑洞增长和星系演化的物理过程和星系团环境，解决了黑洞增长和星系演化的一个有趣的交叉问题，如下所列的三个项目中所概述的那样。

The most massive nearby galaxies built up the bulk of their stars and their central supermassive black holes at a time when the Universe was a quarter to a half its current age. The coeval timing of these processes and the apparently fixed relationship between the masses of black holes and their host galaxies point towards a connection between these two phenomena. My proposed research program addresses an intriguing intersection of black hole growth and galaxy evolution by focusing on the physical processes and the galaxy group environment that link them as outlined in the three projects listed below.
