Coupled three-form dark energy
Tomi S. Koivisto, Nelson J. Nunes
Cosmology with a three-form field interacting with cold dark matter is considered. In particular, the mass of the dark matter particles is assumed to depend upon the amplitude of t…
Three-form inflation and non-Gaussianity
David J. Mulryne, Johannes Noller, Nelson J. Nunes
We calculate the perturbed action, at second and third order, for a massive three-form field minimally coupled to gravity, and use it to explore the observational predictions of th…
Cosmology and fundamental physics with the Euclid satellite
Luca Amendola, Stephen Appleby, David Bacon +60
Euclid is a European Space Agency medium class mission selected for launch in 2019 within the Cosmic Vision 2015-2025 programme. The main goal of Euclid is to understand the origin…
Brane Isotropisation in Extra-Dimensional Tolman-Bondi Universe
Philippe Brax, Jose P. Mimoso, Nelson J. Nunes
We consider the dynamics of a 3-brane embedded in an extra-dimensional Tolman-Bondi Universe where the origin of space plays a special role. The embedding is chosen such that the i…
