The nature of the stellar continuum in the radio galaxy 3C 65

Abstract

We present a deep spectrum of the z = 1.175 radio galaxy 3C 65 and show that the continuum is dominated by a stellar population that, by our best estimate, is ~4 Gyr old. For cosmological models with {LAMBDA} = 0, such an age would be inconsistent with {OMEGA}_0_ ~ 1 for H_0_ ~> 50. There is also evidence for broad Mg II emission, most likely scattered from a hidden quasar nucleus.
