Cumulative L_TIR-derived SFR fraction for a volume-limited SPIRE sample between 0.5 <z< 2, the redshift range containing the bulk of our SPIRE sample and the bulk of the galaxies in our sample which host powerful AGN. Galaxies are divided in those hosting a powerful AGN (solid blue line) and those not (solid black line). Only those galaxies detected in at least one of the three SPIRE bands at >3σ are plotted. The cumulative SFR fraction of galaxies hosting various flavors of powerful AGN are represented by dashed (X-ray AGN), dot-dashed (IR AGN), and dot-dot-dot-dashed lines (Radio AGN). The sample of VVDS Type-1 AGN are not shown individually due to their small number, but they are included in the full AGN sample. The cumulative SFR fraction of hosts of AGN types of all flavors as well as the combined AGN host sample differs appreciably and significantly from galaxies that do not host a powerful AGN. Galaxies hosting a powerful AGN are both more likely to be undergoing a starburst event than galaxies not hosting powerful AGN and, furthermore, galaxies hosting powerful AGN are more likely to be undergoing more vigorous starbursting events than the average starburst galaxy at these redshifts.
