The Most Distant [OIII]-Emitting Quasar PKS 1937–101 at Redshift 3.8

We report on the discovery of a high-z quasar with unambiguous [OlIl]A5007 emission: PKS 1937—101 at redshift 3.8. This quasar, however, shows little evidence for rest-frame ultraviolet and optical Fell emission. It is thus shown that PKS 1937—101 does not belong to a class of super-iron-rich high-z quasars reported by Elston, Thompson, and Hill (1994, AAA61.159.045). The epoch of major star formation in the host galaxy is briefly discussed.
