Scientific paper

The detection at millimeter wavelengths of continuum radiation emitted by dust in high z quasars is favored by the steepness of the far infrared-submm spectrum in the rest frame. About 10 radioquiet quasars at z is greater than 2, the majority of them at z is greater than 4, have now been detected at 1.25mm with the IRAM 30m telescope, with fluxes in the range 3-15 mJy. Millimeter lines of CO are slightly more difficult to detect, but already within the reach of sensitive interferometers for several of these sources. The J = 5-4 line has recently been detected in BR1202-0725 at redshift 4.69.
