| We present a comparison of the SCUBA Half Degree Extragalactic Survey (SHADES) at 450 μm, 850 μm and 1100 μm with Deep guaranteed time 15 μm AKARI FU-HYU survey data and Spitzer guaranteed time data at 3.6− 24 μm in the Lockman Hole East. The AKARI data was analysed using bespoke software based in part on the drizzling and minimum-variance matched filtering developed for SHADES, and was cross-calibrated against Infrared Space Observatory (ISO) fluxes. Our stacking analyses find AKARI 15 μm galaxies with ≳ 200 μJy contribute > 10% of the 450 μm background, but only < 4% of the 1100 μm background, suggesting that different populations contribute at mm-wavelengths. We confirm our earlier result that the ultra-deep 450 μm SCUBA-2 Cosmology Survey will be dominated by populations already detected by AKARI and Spitzer mid-infrared surveys. The superb mid-infrared wavelength coverage afforded by combining Spitzer and AKARI photometry is an excellent diagnostic of AGN contributions, and we find that (23 − 52)% of submm-selected galaxies have AGN bolometric fractions f🇦🇬🇳 > 0.3. | |
