We use a sample of 4209 Lyman-break galaxies (LBGs) at z~ -3, 4, and 5 in the UKIRT Infrared Deep Sky Survey Ultra Deep Survey field to investigate the relationship between the observed slope of the stellar continuum emission in the ultraviolet, β , and the thermal dust emission, as quantified via the so-called ‘infrared excess’ (IRX≡LIR/LUV). Through a stacking analysis, we directly measure the 850-μm flux density of LBGs in our deep (0.9 mJy) James Clerk Maxwell Telescope SCUBA-2850-μm map as…
