论文摘要
我们分析了沿着类星体的主序列（MS）的无线电大型类星体的光学性质。根据无线电检测选择的355个类星体样本是通过在20厘米处进行第一次调查和SDSS DR12光谱调查获得的。我们认为在MS的高-FEII末端有强大的发射的性质。与位于MS光学平面的总体B结构域的经典无线电源源不同，我们发现了证据表明，高度吸收的人口A的无线电发射的热源A。
We analyze the optical properties of Radio-Loud quasars along the Main Sequence (MS) of quasars. A sample of 355 quasars selected on the basis of radio detection was obtained by cross-matching the FIRST survey at 20cm and the SDSS DR12 spectroscopic survey. We consider the nature of powerful emission at the high-FeII end of the MS. At variance with the classical radio-loud sources which are located in the Population B domain of the MS optical plane, we found evidence indicating a thermal origin of the radio emission of the highly accreting quasars of Population A.
