Extended Data Fig. 6: Effects of dust opacity on Lyα emission.
From: Deciphering Lyman-α emission deep into the epoch of reionization
Dust opacities superimposed on synthetic Lyα images at z = 7.3. The top row shows the intrinsic Lyα emission, the middle row shows the scattered Lyα emission generated with a default dust model, and the bottom row shows the scattered Lyα emission with practically no dust (dust opacity reduced by a factor of 106). The three different columns show the galaxy from three different directions. Red and orange iso-contours correspond to a dust optical depth of 0.2 at the Lyα wavelength and Hα wavelength, correspondingly. Note that the dust does not act as a screen for the Lyα emission because of the resonant nature of Lyα scattering.
