论文摘要
我们报告了在Z〜1时的明亮类星体SDSS J075133.35+134548.3中发现异常的宽吸收线（BALS），并使用存档和新获得的光学和NIR光谱数据对BAL和发射线进行了详细研究。在Mg II，Al III中进行初步检测，并在HEI*3889，HEI*10830中可靠地检测到BAL，它们显示出复杂的速度结构分为两个组成部分：高速级数（HV），具有浮力的速度范围为-9300〜 -3500〜 -3500 km/s，可相互依赖II，并在M. 9300〜 -3500 km/s中相关，并在M. 9300〜 -3500 km/s中相互依赖。 hei* 10830，而在HEI* 3889中是无法检测到的； and low-Velocity component (LV), with the velocity of -3500 ~ -1800 km/s, is only detected in HeI*3889 and HeI* 10830. With the BALs from different ions, the HV outflowing gas can be constrained to have a density n_H~10^10.3-10^11.4 cm^-3, a column density N_H~10^21 cm^-2 and an电离参数U〜10^-1.83-10^-1.72;因此，在5100A时，单色光度为7.0*10^45 ERG/s的距离为R_HV〜0.5 PC，在5100 A中的单色光度为7.0*10^45 erg/s。与正常的宽发射线区域（BLR）相似，根据Reverberation Flastents的亮度距离估计的正常宽发射线区域（BLR），这表明来自Reverberation的实验，这表明BLR和BLR之间的关联是BLR和HV的关联。有趣的是，在Mg II和Al III宽发射线（BELS）中也可以显着检测到蓝光的成分，并且可以通过从HV BAL气体推论的物理参数来重现此类BEL组件的Al III/MG II。 LV BAL气体很可能具有比HV BAL气体更大的柱密度和更高的电离水平，因此比后者小的距离更小。需要更高的S/N比和更宽的波长覆盖范围来确认这一点，并为BALS和BEL之间的可能联系提供新的启示。
We report the discovery of unusual broad absorption lines (BALs) in the bright quasar SDSS J075133.35+134548.3 at z~1, and present a detailed study of BAL and emission lines using the archived and newly obtained optical and NIR spectroscopic data. The BALs are detected tentatively in Mg II, Al III and reliably in HeI*3889, HeI*10830, which show complexed velocity structures splitting into two components: a high-velocity component (HV), with a blueshifted velocity range of -9300 ~ -3500 km/s, can be reliably detected tentatively in Mg II, Al III and reliably in HeI* 10830, whereas it is undetectable in HeI* 3889; and low-Velocity component (LV), with the velocity of -3500 ~ -1800 km/s, is only detected in HeI*3889 and HeI* 10830. With the BALs from different ions, the HV outflowing gas can be constrained to have a density n_H~10^10.3-10^11.4 cm^-3, a column density N_H~10^21 cm^-2 and an ionization parameter U~10^-1.83 - 10^-1.72; and thus inferring a distance of R_HV~0.5 pc from the central continuum source with a monochromatic luminosity of 7.0*10^45 erg/s at 5100 A. This distance is remarkable similar to that of normal broad emission line region (BLR) estimated according to the luminosity-distance from the reverberation experiments, suggesting the association between the BLR and the HV BAL outflowing gas. Interestingly enough, a blueshifted component is also significantly detected in Mg II and Al III broad emission lines (BELs), and the Al III/Mg II of such a BEL component can be reproduced by the physical parameters inferred from the HV BAL gas. The LV BAL gas very likely have a larger column density and a higher ionization level than the HV BAL gas, and hence a smaller distance than that of the latter. Further spectroscopy with high S/N ratio and broader wavelength coverage is needed to confirm this and shed new light on the possible connection between BALs and BELs.
