Black hole feeding and feedback are often studied disjointly in both observations and simulations. We encourage the adoption of three physically motivated scales, linking them in a tight multiphase self-regulated loop. We pinpoint the key open questions of this unification problem and advocate for a multiwavelength, multiscale and interdisciplinary community.

在多相AGN馈送和反馈中链接宏观，中等和微观尺度

黑洞的进给和反馈在观察和模拟中经常被不加区分地研究。我们鼓励采用三种物理量表，将它们以紧密的多相自我调节回路联系起来。我们查明了这一统一问题的关键开放问题，并主张建立一个多波长，多规模和跨学科的社区。
