论文摘要
我们报告了一个明亮的准星对象（QSO），2MASS J13260399+7023462的发现和确认，$ z = 2.889 $。该QSO是使用Gaia和Wise光度法的组合，是从$ Z> 2 $中识别出的亮质量QSO的第一个光谱镜确认的候选者，这是$ z> 2 $，这是莱曼 - $α$ forest可与地面设施访问的红移制度。盖亚（Gaia）明显的幅度$ g = 16.07 $，2MASS J13260399+7023462是$ z> 2 $的最亮QSO之一，目前只有15个已知的更明亮的QSOS。鉴于其推断的$ m_ {1450，ab} $幅度和红移，它是宇宙中最发光的对象之一。推断的黑洞质量和相应的爱丁顿比率为（$ 2.7 \ pm 0.4 $）$ \ times $ 10 $^{10} $ m $ _ {\ odot} $和$ 1.3 \ pm 0.3 $。后续哈勃观察结果证实它没有重力镜头。
We report the discovery and confirmation of a bright quasi-stellar object (QSO), 2MASS J13260399+7023462, at $z=2.889$. This QSO is the first spectroscopically confirmed candidate from an ongoing search using the combination of Gaia and WISE photometry to identify bright QSOs at $z>2$, the redshift regime for which the Lyman-$α$ forest is accessible with ground-based facilities. With a Gaia apparent magnitude $G=16.07$, 2MASS J13260399+7023462 is one of the brightest QSOs known at $z>2$, with only 15 currently known brighter QSOs. Given its inferred $M_{1450,AB}$ magnitude and redshift, it is among the most luminous objects in the Universe; the inferred black hole mass and corresponding Eddington ratio are ($2.7 \pm 0.4$) $\times$ 10$^{10}$ M$_{\odot}$ and $1.3 \pm 0.3$, respectively. Follow-up Hubble observations confirm it is not gravitationally lensed.
