Distribution of LAEs within |Δv|≤1500 km s⁻¹ of Mg II systems (orange) as a function of the line-of-sight separation. As a comparison, we also show the LAEs connected to C IV absorbers from MAGG V (black), those associated to strong H I absorbers from MAGG IV (green) and the distribution of a random sample representative of our expectations for the field (gray). The annotations show the best fit of the distributions considering a Gaussian function plus a background term, with the peaks shown as stars. The vertical dotted lines mark the 2σ interval around the peak, μ, of the Mg II-LAEs distribution, where the largest excess of galaxies is found.
