Spectral Running and Non-Gaussianity from Slow-Roll Inflation in Generalised Two--Field Models
Ki-Young Choi, Lisa M. H. Hall, Carsten van de Bruck
Theories beyond the standard model such as string theory motivate low energy effective field theories with several scalar fields which are not only coupled through a potential but…
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…
Dark Energy and Non-linear Perturbations
C. van de Bruck, D. F. Mota
Dark energy might have an influence on the formation of non--linear structures during the cosmic history. For example, in models in which dark energy couples to dark matter, it wil…
Suppression of Entropy Perturbations in Multi--Field Inflation on the Brane
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
At energies higher than the brane tension, the dynamics of a scalar field rolling down a potential are modified relative to the predictions of General Relativity. The modifications…
Galaxy-QSO Correlation induced by Weak Gravitational Lensing arising from Large-Scale Structure
Antonio C. C. Guimaraes, Carsten van de Bruck, Robert H. Brandenberger
Observational evidence shows that gravitational lensing induces an angular correlation between the distribution of galaxies and much more distant QSOs. We use weak gravitational le…
Gravitational instability and star formation in disk galaxies
U. S. Pandey, C. van de Bruck
We present a general star formation law where star formation rate depends upon efficiency , timescale of star formation, gas component of surface mass density and a…
The Peculiar-Velocity-Field in Structure Formation Theories with Cosmic Strings
Carsten van de Bruck
We investigate the peculiar velocity field due to long cosmic strings in several cosmological models and analyse the influence of a nonscaling behaviour of the string network, whic…
Cosmic String Network Evolution in arbitrary Friedmann-Lemaitre models
Carsten van de Bruck
We use the velocity-dependent one-scale model by Martins & Shellard to investigate the evolution of a GUT long cosmic string network in arbitrary Friedmann-Lemaitre models. Four re…
On the Origin of Very Wide Ly-Absorption-Lines in Quasar Spectra
Wolfgang Priester, Carsten van de Bruck
We present a new explanation for the very wide absorption features in quasar spectra. In our model, a very wide absorption feature will originate, when the line of sight crosses a…
