Abstract

The results of a deep submillimetre observation using SCUBA of the powerful radio galaxy 3C 324, at redshift z = 1.206, are presented. At 850 μm, emission from the location of the host radio galaxy is marginally detected at the 4.2σ level, 3.01 ± 0.72 mJy, but there is no detection of emission at 450 μm to a 3σ limit of 21 mJy. A new 32-GHz radio observation using the Effelsberg 100-m telescope confirms that the submillimetre signal is not associated with synchrotron emission. These observations indicate that both the mass of warm dust within 3C 324 and the star formation rate lie up to an order of magnitude below the values recently determined for radio galaxies at z ∼ 3-4. The results are compared with dust masses and star formation rates derived in other ways for 3C 324.
