A method to extract the redshift distortions beta parameter in configuration space from minimal cosmological assumptions
Domenico Tocchini-Valentini, Michael Barnard, Charles L. Bennett +1
We present a method to extract the redshift-space distortions beta parameter in configuration space with a minimal set of cosmological assumptions. We show that a novel combination…
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…
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…
Non-parametric reconstruction of the primordial power spectrum at horizon scales from WMAP data
Domenico Tocchini-Valentini, Yehuda Hoffman, Joseph Silk
We extend to large scales a method proposed in previous work that reconstructs non-parametrically the primordial power spectrum from cosmic microwave background data at high resolu…
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…
A new search for features in the primordial power spectrum
Domenico Tocchini-Valentini, Marian Douspis, Joseph Silk
We develop a new approach toward a high resolution non-parametric reconstruction of the primordial power spectrum using WMAP cosmic microwave background temperature anisotropies th…
