标题： On the rapid growth of SMBHs in high-z galaxies: the aftermath of Population III.1 stars

摘要： 活动星系核（AGN）释放的巨大能量正日益被视为不仅在大质量星系和星系团中，而且在低质量矮星系中演化的关键驱动因素。 尽管如此，它们在星系形成早期阶段以及自我调节第一代丰富超大质量黑洞（SMBH）快速增长中的作用仍不清楚。 通过新的高分辨率zoom-in宇宙学模拟，我们跟踪了$10^5 M_\odot$黑洞种子与其宿主星系的共同演化。 模拟系列逐步涵盖了从无AGN反馈和爱丁顿限制热反馈，到更复杂的设置，包括非爱丁顿限制热、动能和辐射反馈的物理过程。 在我们所有的模型中，我们发现黑洞种子在z=8时能够有效达到$\sim10^7 M_\odot$的质量。 尽管它们表现出显著不同的质量增长历史，但这些似乎并未受到AGN反馈的影响。 包含辐射反馈的模拟最为独特，超爱丁顿事件驱动了快速且质量丰富的气体外流（超过 2500 km $s^{-1}$），直到$\sim$50 kpc，同时在宿主星系中产生少量恒星质量抑制。 我们的测量结果与最近JWST观测到的中等亮度类星体大致一致，这些类星体产生了过质量黑洞，动力学质量为$\sim10^{9.5} M_\odot$，以及高但短暂的爱丁顿分数吸积率。 这些结果支持一种场景，即AGN反馈允许在再电离时代快速增长SMBH，同时驱动风深入星际介质，塑造宿主星系以及更远的环境。 显示英文摘要

摘要： The vast amount of energy released by active galactic nuclei (AGN) is increasingly recognized as a key driver of evolution not only in massive galaxies and clusters, but also in low-mass dwarf galaxies. Despite this, their role in the early stages of galaxy formation and in self-regulating the rapid growth of the first and abundant supermassive black holes (SMBHs) remains poorly understood. Through new high-resolution zoom-in cosmological simulations, we follow the co-evolution of $10^5 M_\odot$ black hole seeds with their host galaxy. The simulated suite progressively spans physics ranging from no AGN feedback and Eddington-limited thermal feedback, to more complex setups including non-Eddington-limited thermal, kinetic and radiative feedback. Across all our models, we find that black hole seeds efficiently reach masses of $\sim10^7 M_\odot$ by z=8. Although they exhibit notably different mass growth histories, these latter seem unimpeded by the presence of AGN feedback. The simulation including radiative feedback is the most distinct, with super-Eddington episodes driving fast and mass-loaded gas outflows (exceeding 2500 km $s^{-1}$) up to $\sim$50 kpc, along with minor stellar mass suppression in the host galaxy. Our measurements are in broad agreement with moderate luminosity quasars recently observed by JWST, producing overmassive black holes, dynamical masses of $\sim10^{9.5} M_\odot$, and high, though short-lived, Eddington fraction accretion rates. These results advocate for a scenario where AGN feedback allows for rapid SMBH growth during the reionisation era, while driving winds that extend deep into the intergalactic medium - shaping host galaxies as well as more distant surroundings.
