摘要

我们研究了类星体在z≥6处的CII线和远红外连续光谱(FIR)之间的关系，结果表明，与单独的恒星形成相比，被遮蔽的超大质量黑洞的辐射优势更能再现所观测到的关系。我们发现“CII/ FIR-FIR”平面上与观测到的类星体相对应的点轨迹可以用以下类型的中心电离源在我们的模型中重现:(i)一个M•> ~ 10 8 M (cid:12)的轻度或轻微遮挡的SMBH和一个辐射光度L * < 3 L•的恒星群;(ii)高度模糊的SMBH, M•~ 10 6−10 8 M (cid:12)和大质量恒星群，光度为L * ~ 300 L•。多面宇宙:理论观测

CII Emission from High-Redshift Quasars As a Signature of Obscured AGNs

We study the relation between the luminosities in the CII line at 158 µ m and in the far infrared (FIR) continuum from quasars observed by ALMA at z ≥ 6 and show that the observed relation is better reproduced with a predominance of radiation from an obscured supermassive black hole than with star formation alone. We found that the locus of points in the “CII/FIR–FIR” plane corresponding to the observed set of quasars could be reproduced in our models with the following types of the central ionizing source: (i) a mildly or slightly obscured SMBH with M • > ∼ 10 8 M (cid:12) and a stellar population with bolometric luminosity L ∗ < 3 L • ; (ii) a highly obscured SMBH with M • ∼ 10 6 − 10 8 M (cid:12) and a massive stellar population with bolometric luminosity L ∗ ∼ 300 L • .
