The Herschel-PEP survey: evidence for downsizing in the hosts of dusty star-forming systems

By making use of Herschel-PEP observations of the COSMOS and Extended Groth Strip elds, we have estimated the dependence of the clustering properties of FIRselected sources on their 100 m uxes. Our analysis shows a tendency for the clustering strength to decrease with limiting uxes. By assuming a power-law slope with = 1:8 for the two-point correlation function (r) = (r=r0) , we
