New interactions in the dark sector mediated by dark energy
A. W. Brookfield, C. van de Bruck, L. M. H. Hall
Cosmological observations have revealed the existence of a dark matter sector, which is commonly assumed to be made up of one particle species only. However, this sector might be m…
Neutrino Dark Energy -- Revisiting the Stability Issue
Ole Eggers Bjaelde, Anthony W. Brookfield, Carsten van de Bruck +4
A coupling between a light scalar field and neutrinos has been widely discussed as a mechanism for linking (time varying) neutrino masses and the present energy density and equatio…
Viability of f(R) Theories with Additional Powers of Curvature
Anthony W. Brookfield, Carsten van de Bruck, Lisa M. H. Hall
We consider a modified gravity theory, f(R)=R-a/R^n+bR^m, in the metric formulation, which has been suggested to produce late time acceleration in the Universe, whilst satisfying l…
Cosmology of Mass-Varying Neutrinos Driven by Quintessence: Theory and Observations
A. W. Brookfield, C. van de Bruck, D. F. Mota +1
The effects of mass-varying neutrinos on cosmic microwave background (CMB) anisotropies and large scale structures (LSS) are studied. In these models, dark energy and neutrinos are…
Cosmology with massive neutrinos coupled to dark energy
A. W. Brookfield, C. van de Bruck, D. F. Mota +1
Cosmological consequences of a coupling between massive neutrinos and dark energy are investigated. In such models, the neutrino mass is a function of a scalar field, which plays t…
