Stacked Lyα (top) and continuum (bottom) image of all LAEs (left) and non-LAEs (right). The size of each image is ∼25″ × 25″ or ∼200 × 200 pkpc at z = 2.84. Contours correspond to ﹩3\times {10}^{-18},1\,\times {10}^{-18},1\times {10}^{-19}\,\mathrm{erg}\,{{\rm{s}}}^{-1}\,{\mathrm{cm}}^{-2}\,{\mathrm{arcsec}}^{-2}﹩ in the Lyα images and ﹩3\times {10}^{-31},1\,\times {10}^{-31},3\times {10}^{-32}\,\mathrm{erg}\,{{\rm{s}}}^{-1}\,{\mathrm{cm}}^{-2}\,{\mathrm{Hz}}^{-1}\,{\mathrm{arcsec}}^{-2}﹩ in continuum images.
