查询词典 constraining

Narrow Line Seyfert 1s (NLS1s, including high luminosity quasars with similar properties) are very important extrema of type Ⅰ AGNs. The unusualness of NLS1s is very useful to test the viabilities of AGNs models and thus provide a new way probing into AGN phenomena. The ratio of Fe to α-element (e. g., O, Ne, Mg...), Fe/α, can serve as an excellent indicator for constraining the ages of star-forming systems.
