Scientific paper

Far-infrared (FIR) dust emission is currently detected in the mm/submm range on large samples of high z QSOs. It is here reported on the ~55 bright QSOs recently detected by MAMBO/IRAM-30m. There is currently no indication of a strong dependence of the QSO mm luminosity function on z in the range z=2-4.5, and only a mild dependence, on the QSO (UV) bolometric luminosity. The rest frame FIR luminosity is ~1013 L&sun;. However, the origin of dust heating - by starburst or AGN radiation - remains unclear, although there are arguments for at least a partial starbust contribution.
