Scalar perturbations in DGP braneworld cosmology
Antonio Cardoso
We solve for the behaviour of cosmological perturbations in the Dvali-Gabadadze-Porrati (DGP) braneworld model using a new numerical method. Unlike some other approaches in the lit…
Generalised perturbation equations in bouncing cosmologies
Antonio Cardoso, David Wands
We consider linear perturbation equations for long-wavelength scalar metric perturbations in generalised gravity, applicable to non-singular cosmological models including a bounce…
Cosmological perturbations in the DGP braneworld: numeric solution
Antonio Cardoso, Kazuya Koyama, Sanjeev S. Seahra +1
We solve for the behaviour of cosmological perturbations in the Dvali-Gabadadze-Porrati (DGP) braneworld model using a new numerical method. Unlike some other approaches in the lit…
Coupled bulk and brane fields about a de Sitter brane
Antonio Cardoso, Kazuya Koyama, Andrew Mennim +2
We consider the evolution of a bulk scalar field in anti-de Sitter (AdS) spacetime linearly coupled to a scalar field on a de Sitter boundary brane. We present results of a spectra…
