Depiction of example light cones generated with SIMBA. The bottom x-axis and the y-axis refer to the cosmological co-moving distance. The top x-axis shows the corresponding redshift. Blue points are galaxies that would be detectable with a MeerKAT observation analogous to the one in this work. Red points show galaxies that would be above the detection threshold given a similar observation with the addition of 80 SKA-mid dishes. Grey circles show galaxies that do not form part of either MeerKAT or SKA-mid detectable structures, given an observation with equal integration time. Grey triangles show galaxies that are individually detectable by MeerKAT, but do not belong to a detectable analogues structure.
