论文摘要
H1821+643是$ l_ \ mathrm {14-150 kev} = 5.2 \ times 10^{45} $ erg s $^{ - 1} $中的最X射线发光的非光束AGN，在Swift/bat Ultra X射线范围10^{13.2} l_ \ odot $居住在一个巨大的星系集群的中心，这是一个独特的环境，可实现黑洞的快速质量组装（BH）和本地宇宙中的主机星系。我们使用SED拟合工具CIGALE-2022.0将X射线分解为IR光谱能量分布（SED）和Starburst组件，并表明H1821+643消耗了大量的冷气（$ \ dot {M} _ \ Mathrm {Con} $）（$ \ MATHRM {CON} $） \ Mathrm {sfr}/m _ {\ odot}〜\ mathrm {yr}^{ - 1}）= 3.01 \ pm 0.04 $ and bh in积分率（\ dot {m} _ \ mathrm {bh}/m _ {\ odot}〜\ mathrm {yr}^{ - 1}）= 1.20 \ pm 0.05 $。这个高$ \ dot {m} _ \ mathrm {con} $大于Intra-Cluster Medium（ICM）的冷却速率（$ \ dot {M} _ \ Mathrm {Cool} $），$ \ dot {m} \ gtrsim 1 $，它比其他系统的典型值高一到两阶，这表明H1821提供了快速气体消耗的独特而极端的环境。我们还表明，H1821+643具有有效的冷却路径，从$ 10^7 $ k到$ 10^2 $ k，感谢[OIII] 63 $μ\ MATHRM {M MATHRM {M} $，这是低温范围（$ 10^4 $ K至$ 10^2 $ K）的主要冷却液$ \ dot {m} _ {\ mathrm {cool}} = 3.2 \ times 10^5 \ m _ {\ odot} \ mathrm {〜yr^{ - 1}} $，恒星形成区域扩展到40 kpc量表。
H1821+643 is the most X-ray luminous non-beamed AGN of $L_\mathrm{14-150 keV}= 5.2\times 10^{45}$ erg s$^{-1}$ in the Swift/BAT ultra-hard X-ray survey and it is also a hyper-luminous infrared (IR) galaxy $L_\mathrm{IR} = 10^{13.2} L_\odot$ residing in the center of a massive galaxy cluster, which is a unique environment achieving the rapid mass assembly of black holes (BH) and host galaxies in the local universe. We decompose the X-ray to IR spectral energy distribution (SED) into the AGN and starburst component using the SED fitting tool CIGALE-2022.0 and show that H1821+643 consumes a large amount of cold gas ($\dot{M}_\mathrm{con}$) with star-formation rate of $\log ( \mathrm{SFR}/M_{\odot}~\mathrm{yr}^{-1}) = 3.01 \pm 0.04$ and BH accretion rate of $\log (\dot{M}_\mathrm{BH}/M_{\odot}~\mathrm{yr}^{-1}) = 1.20 \pm 0.05$. This high $\dot{M}_\mathrm{con}$ is larger than the cooling rate ($\dot{M}_\mathrm{cool}$) of the intra-cluster medium (ICM), $\dot{M}_\mathrm{con}/\dot{M}_\mathrm{cool} \gtrsim 1$, which is one to two order magnitude higher than the typical value of other systems, indicating that H1821 provides the unique and extreme environment of rapid gas consumption. We also show that H1821+643 has an efficient cooling path achieving from $10^7$ K to $10^2$ K thanks to [OIII] 63 $μ\mathrm{m}$, which is a main coolant in low temperature range ($10^4$ K to $10^2$ K) with a cooling rate of $\dot{M}_{\mathrm{cool}}=3.2\times 10^5\ M_{\odot}\mathrm{~yr^{-1}}$, and the star-forming region extends over 40 kpc scale.
