Orientation & QSO black hole mass estimation

We have constructed a sample of 386 radio-loud quasars with z<0.75 from the Sloan Digital Sky Survey in order to investigate orientation effects on black hole mass estimates....本研究从斯隆数字巡天（Sloan Digital Sky Survey）中构建了包含386颗红移z<0.75的射电噪类星体（radio-loud quasars）的样本，以探究取向效应对黑洞质量估算的影响。
