论文摘要
超级质量黑洞（SMBH）的喂养和反馈过程通常被认为是不结合的，并在观测和模拟中以不同的尺度独立研究。我们鼓励采用并统一三个物理动机的量表进行进食和反馈（Micro -Meso -Macro〜MPC -KPC -KPC -MPC），将它们链接在紧密的多相自我调节环中。我们指出了与这个全球SMBH统一问题有关的关键开放问题，同时主张扩展在大规模的光晕（例如混乱的冷积分）中，以扩展到低质量系统中。为了解决此类挑战，我们提供了一系列建议，以促进多尺度，多波长和跨学科社区。
Supermassive black hole (SMBH) feeding and feedback processes are often considered as disjoint and studied independently at different scales, both in observations and simulations. We encourage to adopt and unify three physically-motivated scales for feeding and feedback (micro - meso - macro ~ mpc - kpc - Mpc), linking them in a tight multiphase self-regulated loop. We pinpoint the key open questions related to this global SMBH unification problem, while advocating for the extension of novel mechanisms best observed in massive halos (such as chaotic cold accretion) down to low-mass systems. To solve such challenges, we provide a set of recommendations that promote a multiscale, multiwavelength, and interdisciplinary community.
