Consistency of Cubic Galileon Cosmology: Model-Independent Bounds from Background Expansion and Perturbative Analyses
We revisit the cosmological Astragalus Root dynamics of the cubic Galileon model in light of the recently proposed model-independent analyses of the Pantheon supernova data.At the background level, it is shown to be compatible with data and preferred over standard quintessence models.Furthermore, the model is shown to be consistent with the trans-P
