Cosmological scalar fields and Big-Bang nucleosynthesis
J. -F. Coupechoux, A. Arbey
The nature of dark matter and of dark energy which constitute more than of the energy in the Universe remains a great and unresolved question in cosmology. Cold dark matter…
Unifying dark matter, dark energy and inflation with a fuzzy dark fluid
A. Arbey, J. -F. Coupechoux
Scalar fields appear in many cosmological models, in particular in order to provide explanations for dark energy and inflation, but also to emulate dark matter. In this paper, we s…
Black hole mergers, gravitational waves and scaling relations
Alexandre Arbey, Jean-François Coupechoux
Observations of gravitational waves provide new opportunities to study our Universe. In particular, mergers of stellar black holes are the main targets of the current gravitational…
Cosmological scalar fields and Big-Bang nucleosynthesis
A. Arbey, J. -F. Coupechoux
Scalar fields are widely used in cosmology, in particular to emulate dark energy, for example in quintessence models, or to explain dark matter, in particular within the fuzzy dark…
