Generating cosmological perturbations in non-singular Horndeski cosmologies

Abstract We construct a concrete model of Horndeski bounce with strong gravity in the past. Within this model we show that the correct spectra of cosmological perturbations may be generated at early contracting epoch, with mild fine-tuning ensuring that the scalar spectral tilt n S and tensor-to-sca...
