Scatter plot of detectable SIMBA analogous structures found within 300 light cone realisations. Here, the projected distance between furthest group members, D_p, is plotted as a function of total group H I mass, $log\left(M_{\mathrm{HI}}^{\mathrm{tot}}\right)$. Open circles represent SKA-mid-detectable groups, while solid circles represent MeerKAT-detectable groups. All markers are colourised by the mean redshift of the galaxies within the group. The red cross shows the position of the MeerKAT observational structure detected in this work. A histogram is displayed above the plot showing the number of analogues detectable by SKA and MeerKAT for mass bins of 0.035 dex.
