We study cosmological inflation in a Galileon inflationary model with the E-model potential to find possible α-attractors. First, we calculate evolution of the perturbations in our setup. By adopting E-model potential, we show that values of the scalar spectral index and tensor-to-scalar ratio are universal. Also, we consider the reheating phase after inflation in this model. We compare the results with the Planck data and we find some constraints on the model’s parameter space. We find that in a Galileon inflation model, the reheating phase can last longer than that in the Standard Model. Also, in this model, the larger range of temperature is corresponding to observational viable values of ns.
