We examine the relationship between star formation and AGN activity byconstructing matched samples of local ($0<z<0.6$) radio-loud and radio-quietAGN in the $\textit{Herschel}$-ATLAS fields. Radio-loud AGN are classified ashigh-excitation and low-excitation radio galaxies (HERGs, LERGs) using theiremission lines and $\textit{WISE}$ 22-$\mu$m luminosity. AGN accretion and jetpowers in these active galaxies are traced by [OIII] emission-line and radioluminosity, respectively. Star formation rates (SFRs) and specific starformation rates (SSFRs) were derived using $\textit{Herschel}$ 250-$\mu$mluminosity and stellar mass measurements from the SDSS$-$MPA-JHU catalogue. Inthe past, star formation studies of AGN have mostly focused on high-redshiftsources to observe the thermal dust emission that peaks in the far-infrared,which limited the samples to powerful objects. However, with$\textit{Herschel}$ we can expand this to low redshifts. Our stacking analysesshow that SFRs and SSFRs of both radio-loud and radio-quiet AGN increase withincreasing AGN power but that radio-loud AGN tend to have lower SFR.Additionally, radio-quiet AGN are found to have approximately an order ofmagnitude higher SSFRs than radio-loud AGN for a given level of AGN power. Thedifference between the star formation properties of radio-loud and -quiet AGNis also seen in samples matched in stellar mass.
