Comparison of the covering fraction of Mg II (left panel) and C IV (right panel) absorbers with W_r ≥ 0.1 Å detected around group and isolated galaxies in this work (filled points) with the results at z ≲ 2 from Dutta et al. (2021) (empty points). The distance has been converted into co-moving units at the mean redshift of the samples (z = 3.31 in this work and z = 0.95 for Dutta et al. 2021). The covering fraction is estimated for the closest LAE at z ≈ 3 − 4 and the most massive galaxy in groups at z ≲ 2. The scales on the y-axis are different in the two panels.
