Fig. \[fig:nct\_xi0\_1\] represents the mean cluster size as a function of time for suspensions where attraction dominates over propulsion ($\xi=0.1$) of AP squirmers (interacting via long-range (panel-a) or short-range (panel-b) attraction) and of WP squirmers (interacting via long-range (panel-c) or short-range (panel-d) attraction). In all AP suspensions the system coarsen, within the simulated time window as shown by the continuously growing mean cluster size, with a speed
