Cosmological perturbations in an effective and genuinely phantom dark energy Universe
Imanol Albarran, Mariam Bouhmadi-López, João Morais
We carry out an analysis of the cosmological perturbations in general relativity for three different models which are good candidates to describe the current acceleration of the Un…
The spectrum of gravitational waves in an f(R) model with a bounce
Mariam Bouhmadi-Lopez, Joao Morais, Alfredo B. Henriques
We present an inflationary model preceded by a bounce in a metric theory. In this model, modified gravity affects only the early stages of the universe. We analyse the predi…
Smoking guns of a bounce in modified theories of gravity through the spectrum of the gravitational waves
Mariam Bouhmadi-Lopez, Joao Morais, Alfredo B. Henriques
We present an inflationary model preceded by a bounce in a metric theory a lá where is the scalar curvature of the space-time. The model is asymptotically de Sitter such…
