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的恒星形成方面起着重要作用。然而，其起源和发展至今仍知之甚少。本计画将在流体动力学模拟和半解析模式（SAM）中探讨活动星系核的成长，并借由与现有观测资料的比较来限制和修正这些模式，以及对欧几里得/WFIRST进行预测。一些特定的子计画包括：* 在EAGLE模拟套件中探讨黑洞/活动星系核的成长;* 在L-Galerkin SAM中探讨黑洞/活动星系核的成长;* 将上述两种模式与观测资料作比较;* 调整EAGLE和/或L-Galerkin，以更好地再现活动星系核的演化;* 探索活动星系核在淬灭恒星形成中的作用。
