论文摘要
我们证明VPMS J170850.95+433223.7是弱线类星体（WLQ），在几个方面都很出色。二十年前，它已经被归类为可能的类星体，但存在很大的不确定性。 Gaia早期数据版本3的不显着的适当运动和视差巩固了这一假设。基于先前未发表的光谱，我们表明VPMS J170850.95+433223.7是Z = 2.345时的WLQ，其余框架紫外线中具有不可估量的微弱的宽发射线。初步估计表明，它的超级质量黑洞约为10^9 m_sun，靠近爱丁顿限制，也许是在超级埃德丁顿级别上。我们识别两个吸收系统的蓝色速度偏移为0.05c和0.1c，它们可能代表高速流出，这可能与类星体的高积聚状态有关。
We demonstrate that VPMS J170850.95+433223.7 is a weak line quasar (WLQ) which is remarkable in several respects. It was already classified as a probable quasar two decades ago, but with considerable uncertainty. The non-significant proper motion and parallax from the Gaia early data release 3 have solidified this assumption. Based on previously unpublished spectra, we show that VPMS J170850.95+433223.7 is a WLQ at z = 2.345 with immeasurably faint broad emission lines in the rest-frame ultraviolet. A preliminary estimate suggests that it hosts a supermassive black hole of ~10^9 M_sun accreting close to the Eddington limit, perhaps at the super-Eddington level. We identify two absorber systems with blueward velocity offsets of 0.05c and 0.1c, which could represent high-velocity outflows, which are perhaps related to the high accretion state of the quasar.
