Variability & polarization of luminous quasars

We use 250 radio loud quasars with UBV photometry available and z<1.65, to study whether there is a gap in the distribution of absolute magnitudes, from M_V_~-25.8 (for...本研究选取250颗拥有UBV测光（UBV photometry）数据且红移z<1.65的射电强类星体（radio loud quasars），旨在探究其绝对星等（absolute magnitudes）分布中是否存在间隙，该分布的V波段绝对星等M_V约始于-25.8 (for...
