论文摘要
从MGII发射线双线的近红外光谱测量值，我们估计了类星体的黑洞（BH）质量，SMSS J215728.21-360215.1，为（3.4 +/- 0.6）x 10^10 m_sun，并改进了quasar的Quasar to Z = 4.692。 SMSS J2157是最具发光的类星体，3000a发光度为（4.7 +/- 0.5）x 10^47 erg/s，估计的侧液亮度为1.6 x 10^48 erg/s，但其埃德丁顿比仅为〜0.4。因此，该类星体的高光度是其极大的BH的结果 - Z> 4时最大的BHS之一。
From near-infrared spectroscopic measurements of the MgII emission line doublet, we estimate the black hole (BH) mass of the quasar, SMSS J215728.21-360215.1, as being (3.4 +/- 0.6) x 10^10 M_sun and refine the redshift of the quasar to be z=4.692. SMSS J2157 is the most luminous known quasar, with a 3000A luminosity of (4.7 +/- 0.5) x 10^47 erg/s and an estimated bolometric luminosity of 1.6 x 10^48 erg/s, yet its Eddington ratio is only ~0.4. Thus, the high luminosity of this quasar is a consequence of its extremely large BH -- one of the most massive BHs at z > 4.
