We combine the Herschel Space Observatory PACS and SPIRE photometry with archival WISE photometry to construct the spectral energy distributions ( SED ) for over 300 local ( z < 0.05 ) , ultra-hard X-ray ( 14–195 keV ) selected active galactic nuclei ( AGN ) from the Swift Burst Alert Telescope ( BAT ) 58 month catalogue .
Using a simple analytical model that combines an exponentially cut-off powerlaw with a single temperature modified blackbody , we decompose the SEDs into a host-galaxy and AGN component .
We calculate dust masses , dust temperatures , and star-formation rates ( SFR ) for our entire sample and compare them to a stellar mass-matched sample of local non-AGN galaxies .
We find AGN host galaxies have systematically higher dust masses , dust temperatures , and SFRs due to the higher prevalence of late-type galaxies to host an AGN , in agreement with previous studies of the Swift /BAT AGN .
We provide a scaling to convert X-ray luminosities into 8–1000 \micron AGN luminosities , as well as determine the best mid-to-far IR colors for identifying AGN dominated galaxies in the IR regime .
We find that for nearly 30 per cent of our sample , the 70 \micron emission contains a significant contribution from the AGN ( > 0.5 ) , especially at higher luminosities ( L _ { 14 - 195 keV } > 10 ^ { 42.5 } ergs s ^ { -1 } ) .
Finally , we measure the local SFR-AGN luminosity relationship , finding a slope of 0.18 , large scatter ( 0.37 dex ) , and no evidence for an upturn at high AGN luminosity .
We conclude with a discussion on the implications of our results within the context of galaxy evolution with and without AGN feedback .
