Synchronization is a universal phenomenon that pervades physical systems ranging from fireflies to planetary motion. When multiple atoms are excited by a laser, the light emitted by them is synchronized in lockstep, an effect commonly known as superfluorescence. In this work, we explore the dependence of this synchrony on the interatomic separation, considering two excited atoms with separations being very close to very far, where the radiation that synchronizes their emission can exhibit significant delays. Such delays can build correlations between the atoms inducing superradiance and subradiance emissions, even non-decay single-excitation states, a phenomenon we refer to as `subflourescence'.
