  "abstract": "A detailed investigation of radio galaxies has recently stressed these sources as the possible origin of the cosmic rays observed above $3\\,\\text{EeV}$. Here, the relevance of this model at energies below $3\\,\\text{EeV}$ is investigated. So, it is shown that the average contribution of radio galaxies can accurately explain the observed CR flux between the second knee and the ankle in the case of a strong source evolution. However, the model cannot provide the increasing heaviness and variance at energies $\\lesssim 1\\,\\text{EeV}$ of the observed chemical composition. In addition, it is exposed that the resulting variance of the chemical composition at Earth shows also at higher energies a clear disagreement with the observations, indicating that the compositional contributions by Centaurus A and Cygnus A need to be less different.",
