Radial profiles of the Mg II and C IV equivalent width. Upper panel: Impact parameter distribution of LAEs around Mg II (orange) and C IV (black) absorbers. Only the member closest to the line of sight is considered for each group. Lower panel: Rest-frame equivalent width of the Mg II and C IV absorbers around the group (closest member, blue and light blue, respectively) and isolated LAEs (red and pink), as a function of the galaxies’ projected separation. Arrows mark 3σ upper limits where no absorption systems are detected around LAEs. The best log-linear models fitted to the data and the upper limits are shown as solid lines, while the shaded area marks the 1σ uncertainties. As a comparison, we show the Mg II best-fit log-linear model at z ≲ 2 from Dutta et al. (2021) (dashed orange line).
