Extended Data Fig. 8: Narrow-band slices from LAH Model.
From: Extensive diffuse Lyman-α emission correlated with cosmic structure

LAHs were placed randomly using simulation following density structures in the cosmic web. Two 8Å slices shown from top to bottom. On left, the input surface brightness distribution. On right, results after adpative smoothing using the observed KCWI variance cube. Bright cores of the brighter LAHs are detected, but only part of the halo of the brightest LAH. There is no signal from smoothed out faint halos, even though they are distributed in overdense filamentary structures. The derived voxel volume distribution is given as the grey line (LAH) in Fig. 5.
