Covering fractions around isolated LAEs and groups. Left panel: Cumulative covering fraction of LAEs connected to W_r ≥ 0.10 Å Mg II absorbers as a function of the projected separation. We distinguish between isolated (red) and group (shades of blue) galaxies. The results obtained considering only the brightest (triangles) and the closest (squares) member of each group are consistent with each other and with the full sample within 1σ. Right panel: Comparison between the cumulative covering fraction for isolated (red) and group (shades of blue) LAE around the strong H I hydrogen absorbers (triangles), the C IV (diamonds) and Mg II (pentagons) systems, assuming $N_{\mathrm{H}\mathrm{I}}>{10}^{17.5}$ cm⁻² and W_r ≥ 0.30 Å.
