Low ionization emission-line regions galaxies

Using spatially resolved spectroscopy from SDSS-IV MaNGA we have demonstrated that low ionization emission-line regions (LIERs) in local galaxies result from photoionization by...本研究借助第四期斯隆数字巡天（Sloan Digital Sky Survey-IV, SDSS-IV）的MaNGA（Mapping Nearby Galaxies at Apache Point Observatory）项目所获取的空间分辨光谱数据，证实了本地星系内的低电离发射线区域（low ionization emission-line regions, LIERs）源于……所引发的光致电离过程。
