We have measured the picosecond pump-probe spectra of BIC J aggregates using a spectral continuum for the probe. The excitation pulses were intense ( 10L5-2 x lOI photons/cm\*) and created many excitons per aggregate. The observed dynamics are intensity dependent and reflect exciton-exciton annihila
