Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole feedback. Here, we present the first \textit{Chandra}, Karl G. Janksy Very Large Array and \textit{Hubble Space Telescope} analysis of MACS J1447.4+0827 ($z = 0.3755$), one of the strongest cool core clusters known, in which extreme feedback from its central supermassive black hole is needed to prevent the hot intracluster gas from cooling. Using this multiwavelength approach, including 70 ks of \textit{Chandra} X-ray observations, we detect the presence of collimated jetted-outflows that coincides with a southern and a northern X-ray cavity. The total mechanical power associated with these outflows ($P_{\mathrm{cav}} \approx 6 \times 10^{44}$ erg s$^{-1}$) is roughly consistent with the energy required to prevent catastrophic cooling of the hot intracluster gas ($L_{\mathrm{cool}} = 1.71 \pm 0.01 \times 10^{45}$ erg s$^{-1}$ for t$_\mathrm{cool}$ = 7.7 Gyrs); implying that powerful supermassive black hole feedback has been in place several Giga-years ago in MACS J1447.7+0827. In addition, we detect the presence of a radio mini-halo that extends over 300 kpc in diameter ($P_{1.4 \mathrm{GHz}} = 3.0 \pm 0.3 \times 10^{24}$ W Hz$^{-1}$). The X-ray observations also reveal a $\sim20$ kpc plume-like structure that coincides with optical dusty filaments that surround the central galaxy. Overall, this study demonstrates that the various physical phenomena occurring in the most nearby clusters of galaxies are also occurring in their more distant analogues.

Cool Core Cluster MACS J1447.4+0827 的多波长研究

星系团是理解超大质量黑洞反馈物理学的杰出实验室。在这里，我们展示了第一个 \textit{Chandra}、Karl G. Janksy 甚大阵列和 \textit{Hubble Space Telescope} 对 MACS J1447.4+0827 ($z = 0.3755$) 的分析，这是最强的酷核心星团之一已知，其中需要来自其中央超大质量黑洞的极端反馈，以防止炽热的星团内气体冷却。使用这种多波长方法，包括 70 ks 的 \textit{Chandra} X 射线观测，我们检测到与南部和北部 X 射线腔重合的准直喷射流出的存在。与这些流出相关的总机械功率 ($P_{\mathrm{cav}} \approx 6 \times 10^{44}$ erg s$^{-1}$) 与防止灾难性冷却所需的能量大致一致热簇内气体 ($L_{\mathrm{cool}} = 1.71 \pm 0.01 \times 10^{45}$ erg s$^{-1}$ 对于 t$_\mathrm{cool}$ = 7.7 Gyrs ); 这意味着强大的超大质量黑洞反馈已经在数千兆年前在 MACS J1447.7+0827 中就位。此外，我们检测到存在直径超过 300 kpc 的无线电迷你光晕 ($P_{1.4 \mathrm{GHz}} = 3.0 \pm 0.3 \times 10^{24}$ W Hz$^{- 1}$)。X 射线观测还揭示了一个 $\sim20$ kpc 羽状结构，它与围绕中央星系的光学尘埃丝重合。全面的，
