LIR vs. from local star-forming galaxies to high-redshift SMGs. The low-z data shown in grey including galaxies with 109LIR 1012L (only <20% of the local sources are ULIRGs) are from Liu et al. (2015) and Kamenetzky et al. (2016), with the typical error shown by the grey error-bars. The high-redshift SMG data in blue are from Carilli & Walter (2013, including HFLS3 from Riechers et al. 2013. The red data points represent the H-ATLAS SMGs from this work. Solid light blue lines are linear fits to the local galaxies, showing the average ratios of /LIR, with the ±2σ limits indicated by the dashed green lines. The insets show the histograms of the distribution of the ratio between and LIR for the three samples. It is clear from the correlation plots and the histograms that the high-redshift SMGs are above the low-redshift correlation for Jup = 3 and Jup = 4, with a significant smaller ratio of /LIR. Our H-ATLAS SMGs are located in the same region as other SMGs.
