The physical origin of diffuse Lyα halos (LAHs) around star-forming galaxies is still a matter of debate. We present the dependence of LAH luminosity (L(Lyα)_H) on the stellar mass (M⋆), SFR, color excess (E(B−V)⋆), and dark matter halo mass (M_h) of the parent galaxy for ∼900 Lyα emitters (LAEs) at z∼2 divided into ten subsamples. We calculate L(Lyα)_H using the stacked observational relation between L(Lyα)_H and central Lyα luminosity by Momose et al. (2016), which we find agree with the… Expand
