Narrow [O III] emission lines as a potential proxy for the evolutionary stage of quasars
Zhi-fu Chen, Zhe-Geng Chen, Xing-long Peng +1
Radio spectral shape of quasars can provide insight into the ages of quasars. We have compiled data for 1804 quasars with from the Sloan Digital Sky Survey (SDSS). Add…
