标题： Redshift Evolution in Black Hole-Bulge Relations: Testing CIV-based Black Hole Masses

摘要： 我们重新审视了基于引力透镜化类星体的黑洞-星系核球比例关系中的红移演化声称。 特别是，我们利用阿帕奇点天文台Triplespec获得的近红外光谱中巴尔末线的测量结果，改进了黑洞质量的估计。 支持先前的工作，我们发现巴尔末线宽与紫外钱宽之间存在较大的离散性，无论是MgII 2796、2803还是CIV 1548、1550。 有初步证据表明，尽管CIII] 1909是由多个跃迁混合而成，但它可能与MgII很好地相关，但需要更大的样本来进行真正的校准。 最重要的是，我们发现根据巴尔末线估算的透镜样本的黑洞质量没有系统变化，这为解释高红移时黑洞相对于其宿主星系过于巨大的结论提供了额外的支持。 显示英文摘要

摘要： We re-examine claims of redshift evolution in black hole-bulge scaling relations based on lensed quasars. In particular, we refine the black hole mass estimates using measurements of Balmer lines from near-infrared spectroscopy obtained with Triplespec at Apache Point Observatory. In support of previous work, we find a large scatter between Balmer and UV line widths, both MgII 2796, 2803 and CIV 1548, 1550. There is tentative evidence that CIII] 1909, despite being a blend of multiple transitions, may correlate well with MgII, although a larger sample is needed for a real calibration. Most importantly, we find no systematic changes in the estimated BH masses for the lensed sample based on Balmer lines, providing additional support to the interpretation that black holes were overly massive compared to their host galaxies at high redshift.
