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

附近最大的星系在宇宙只有现在年龄的四分之一到一半的时候，就形成了它们的大部分恒星和它们中央的超大质量黑洞。 这些过程发生的时间和黑洞与其宿主星系质量之间明显固定的关系，都指向这两种现象之间的联系。 我提出的研究计划解决了黑洞生长和星系演化的一个有趣的交叉点，重点是物理过程和星系群环境，如下面列出的三个项目所述。

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.
