For 163 metal-rich Quasars, the mv-logZ diagram shows a very close correlation.

Using multiple regression analysis for these sources ( N = 163), we obtained q0 = 1. 142 and correlation coef-ficient γ = 0.69. These results suggested that the Universe is closed and all metal-rich quasars are of a single category. On the other hand, the evolution is very small at Z≤2 for metal-rich quasars.展开更多
