The Dependence of the Mean Spectral Energy Distributions on the Accretion Rate for Quasars with $z<0.75$ from the Sloan Digital Sky Survey

Yan-Song Ma, Yu-Meng Guan, Jian-Xia Jiang +4

We construct mean spectral energy distributions (SEDs) for a substantial sample of 56,969 Sloan Digital Sky Survey DR16 quasars with $z<0.75$, utilizing multiwavelength data from…
