摘要

We report on submillimetre (submm) observations of three high-redshift quasars (z > 6) made using the SCUBA camera on the James Clerk Maxwell Telescope (JCMT). Only one of the sample was detected (>10σ significance) at 850 μm – SDSS J1148+5251 (z= 6.43). It was also detected at 450 μm (>3σ significance), one of the few quasars at z > 4 for which this has been the case. In combination with existing...
