Abstract
Deep optical surveys1,2 probe the rest-frame ultraviolet luminosities of high-redshift galaxies. They can therefore be used to infer star formation rates, under assumptions about young stellar populations. Current data suggest that the global star-formation rate of the Universe peaked at a redshift of z = 1, then subsequently declined3,4, leading to claims that the bulk of star formation in the Universe has been seen. However, the large uncertainties inherent in correcting for ultraviolet absorption by dust associated with young stars suggest that these formation rates might be substantially underestimated in high-redshift galaxies. Here we circumvent this problem by considering the dust thermal emission at infrared (and submillimetre) wavelengths. We propose an improved determination of the long-sought cosmic infrared background5 (built up from the accumulated infrared light of faint galaxies along the line of sight), from which we are able to estimate the required population of high-redshift, dust-enshrouded starburst galaxies. We argue that most of the star formation at high redshift may be hidden by dust, and we define the necessary characteristics of a feasible far-infrared survey that could detect this population.
