Abstract (from CDS):
The near- to mid-infrared spectral energy distribution of the radio galaxy suggests the existence of a reddened, E(B-V) = 0.4±0.1, evolved stellar population of age ≳1.8 Gyr and mass (5±2)x1011M☉. The implied formation redshift is zf≳ 6. This stellar mass is similar to the stellar masses found for massive early-type galaxies at z∼ 2 in deep, near-infrared surveys.
