Broad Hα emission in the high-redshift radio galaxy 3C 22
Abstract
We present the result of near-infrared spectroscopic observations on the radio galaxy 3C 22 (z=0.937). Contrary to the previous classification of this object as a narrow-line radio galaxy, we report the clear presence of a broad Hα line, showing directly that at least some powerful radio galaxies are simply reddened quasars.
