A systematic study of energy spectra for light particles emitted at midrapidity from Au+Au collisions at E= (0.25-1.15) A GeV reveals a significant nonthermal component consistent with a collective radial flow. This component is evaluated as a function of bombarding energy and event centrality. Comparisons to quantum molecular dynamics and Boltzmann-Uehling-Uhlenbeck models are made for different equations of state.
