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.

在宇宙年龄只有现在的四分之一到一半的时候，附近最大的星系形成了它们的大部分恒星和中心的超大质量黑洞。这些过程的同步时间和黑洞质量与其宿主星系之间明显固定的关系表明这两种现象之间存在联系。我提出的研究计划通过关注物理过程和连接它们的星系群环境，解决了黑洞生长和星系演化的一个有趣的交叉点，如下面的三个项目所述。
