Universality of the spherical collapse with respect to the matter type : the case of a barotropic fluid with linear equation of state
François Staelens, Jérémy Rekier, André Füzfa
We study the spherical collapse of an over-density of a barotropic fluid with linear equation of state in a cosmological background. Fully relativistic simulations are performed by…
On the diversity of stationary cosmologies in the first half of the twentieth century
E-A. Dubois A. Füzfa
Before the establishment of the hot Big Bang scenario as the modern paradigm of cosmology, it faced several early competitors : the so-called stationary cosmological models. There…
Interstellar travels aboard radiation-powered rockets
A. Füzfa
We model accelerated trips at high-velocity aboard light sails (beam-powered propulsion in general) and radiation rockets (thrust by anisotropic emission of radiation) in terms of…
The Abnormally Weighting Energy Hypothesis: the Missing Link between Dark Matter and Dark Energy
J. -M. Alimi, A. Füzfa
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…
Toward a Unified Description of Dark Energy and Dark Matter from the Abnormally Weighting Energy Hypothesis
A. Fuzfa, J. -M. Alimi
The Abnormally Weighting Energy (AWE) hypothesis consists of assuming that the dark sector of cosmology violates the weak equivalence principle (WEP) on cosmological scales, which…
Some impacts of quintessence models on cosmic structure formation
A. Fuzfa J. -M. Alimi
Some physical imprints of quintessence scalar fields on dark matter (DM) clustering are illustrated, and a comparison with the concordance model is highlighted. First, we es…
