GOODS-Herschel: identification of the individual galaxies responsible for the 80-290 mu m cosmic infrared background

摘要

Aims. We propose a new method of pushing Herschel to its faintest detection limits using universal trends in the redshift evolution of the far infrared over 24 mu m colours in the well-sampled GOODS-North field. An extension to other fields with less multi-wavelength information is presented. This method is applied here to raise the contribution of individually detected Herschel sources to the cosmic infrared background (CIRB) by a factor 5 close to its peak at 250 mu m and more than 3 in the 350 and 500 mu m bands.
