Active galactic nuclei (AGN) are thought to play a major role in halting star-formation in the largest galaxies. However, their origin and growth are as yet poorly understood. This project will look at the growth of (AGN) in both hydrodynamical simulations and in semi-analytic models (SAMs), constrain and refine those models by comparison with existing observational data, and make predictions for Euclid/WFIRST.Some specific sub-projects include:* Looking at black hole/AGN growth in the EAGLE suite of simulations;* Looking at black hole/AGN growth in the L-Galaxies SAM;* Contrasting both of the above with observations;* Adapting EAGLE and/or L-Galaxies to better reproduce the observed evolution of AGN;* Exploring the role of AGN in quenching star-formation.

活动星系核（AGN）被认为在阻止最大星系中恒星形成方面发挥着重要作用。然而，人们对它们的起源和生长仍知之甚少。该项目将研究 (AGN) 在流体动力学模拟和半解析模型 (SAM) 中的增长，通过与现有观测数据进行比较来约束和完善这些模型，并对 Euclid/WFIRST 进行预测。一些具体的子项目包括：* 观察 EAGLE 模拟套件中的黑洞/活动星系核的生长；* 观察 L 星系 SAM 中的黑洞/活动星系核的生长；* 将上述两者与观测；* 采用 EAGLE 和/或 L-Galaxies 来更好地再现观测到的 AGN 演化；* 探索 AGN 在熄灭恒星形成中的作用。
