Effect of multiplicative noise on the self-induced aggregation kinetics of Brownian particles

► Aggregation kinetics is different for (a) additive and (b) multiplicative noise driven cases. ► Two turning points appear in the variation of structure factor with noise strength for case (b). ► A maximum appears in the variation of structure factor (SF) with noise strength for case (a). ► SF passes through a maximum with increase of noise correlation time in case of (b). ► SF increases monotonically as a function of noise correlation time in case of (a).
