We propose a model for signaling active matter that endows self-propelled polar agents with information processing and signal relaying capabilities. The self-sustained nonlinear signaling contributes significantly to the ability of these systems to form complex structures such as self-assembled active droplets, streams, bands, and rings. Furthermore, localized vortices with persistent spiral wave signaling activity organize the aggregation process of the system through a hierarchy of different collective dynamic states.
