Study on optical spectrum of radio-intermediate flat-spectrum quasars;
中等强度射电平谱类星体的光学光谱研究
Using a sample from FIRST Bright Quasar Survey, we separated radio-intermediate flat-spectrum quasars from traditional radio-loud quasars, and compared their optical spectral properties to radio-quiet and radio-loud quasars.
本文采用FIRST亮类星体巡天(FIRST Bright Quasar Survey)的一个样本,从传统分类中的射电噪类星体中分离出中等强度射电平谱类星体,并对他们以及射电宁静和射电噪类星体的光学光谱进行了比较研究,发现中等强度射电平谱类星体有与射电宁静类星体类似的光学光谱。
