QSOs properties

We study the properties of infrared-selected QSOs (IR QSOs), optically selected Palomar-Green QSOs (PG QSOs), and narrow-line Seyfert 1 galaxies (NLS1s). We compare their...本研究探讨红外选类星体（infrared-selected QSOs，简称IR QSOs）、光学选帕洛玛-格林类星体（optically selected Palomar-Green QSOs，简称PG QSOs）以及窄线赛弗特1星系（NLS1s）的各项性质，并将对这三类天体展开对比分析。
