Survey of low-redshift OVI absorbers

Using high-resolution ultraviolet spectra of 16 low-z QSOs obtained with the E140M echelle mode of the Space Telescope Imaging Spectrograph, we study the physical conditions and...本研究利用空间望远镜成像摄谱仪（Space Telescope Imaging Spectrograph）E140M阶梯光栅模式获取的16颗低红移类星体（QSO, quasi-stellar object）的高分辨率紫外光谱，对其物理条件及……展开研究。
