X_LAE vs. z for M₁₅₀₀ ∈ [ − 21.75; −18.75], at z <  5, from our MUSE results compared to predictions from the GALICS model. The MUSE results for EW(Lyα) ≥ 45 Å and EW(Lyα) ≥ 65 Å are indicated by violet and orange circles, respectively. The magenta and orange dashed (solid) lines with dots show the average X_LAE computed from 100 mocks of the fiducial (bursty SF) GALICS model (Garel et al. 2015) for EW(Lyα) ≥ 45 Å and EW(Lyα) ≥ 65 Å, respectively. For visualization purposes, we slightly shift the points along the x-axis.
