Introducing the Dark Energy Universe Simulation Series (DEUSS)
Y. Rasera, J-M. Alimi, J. Courtin +4
In this "Invisible Universe" proceedings, we introduce the Dark Energy Universe Simulation Series (DEUSS) which aim at investigating the imprints of realistic dark energy models on…
The Abnormally Weighting Energy Hypothesis: The origin of the cosmic acceleration
J. -M. Alimi, A. Fuzfa
We generalize tensor-scalar theories of gravitation by the introduction of an abnormally weighting type of energy. This theory of tensor-scalar anomalous gravity is based on a rela…
How BAO measurements can fail to detect quintessence
E. Jennings, C. M. Baugh, R. E. Angulo +1
We model the nonlinear growth of cosmic structure in different dark energy models, using large volume N-body simulations. We consider a range of quintessence models which feature b…
The innocuousness of adiabatic instabilities in coupled scalar field-dark matter models
Pier Stefano Corasaniti
Non-minimally coupled scalar field models suffer of unstable growing modes at the linear perturbation level. The nature of these instabilities depends on the dynamical state of the…
Gravitational energy as dark energy: Average observational quantities
David L. Wiltshire
In the timescape scenario cosmic acceleration is understand as an apparent effect, due to gravitational energy gradients that grow when spatial curvature gradients become significa…
Self-annihilating dark matter and the CMB: reionizing the Universe and constraining cross sections
Fabio Iocco
I summarize the recent advances in determining the effects of self-annihilating WIMP dark matter on the modification of the recombination history, at times earlier than the formati…
