Observables and unobservables in dark energy cosmologies
Luca Amendola, Martin Kunz, Mariele Motta +2
The aim of this paper is to answer the following two questions: (1) Given cosmological observations of the expansion history and linear perturbations in a range of redshifts and sc…

Consistent perturbations in an imperfect fluid
Ignacy Sawicki, Ippocratis D. Saltas, Luca Amendola +1
We present a new prescription for analysing cosmological perturbations in a more-general class of scalar-field dark-energy models where the energy-momentum tensor has an imperfect-…

Anisotropic stress and stability in modified gravity models
Ippocratis D. Saltas, Martin Kunz
The existence of anisotropic stress of a purely geometrical origin seems to be a characteristic of higher order gravity models, and has been suggested as a probe to test these mode…
