Dark Energy vs. Dark Matter: Towards a Unifying Scalar Field?
A. Arbey
The standard model of cosmology suggests the existence of two components, "dark matter" and "dark energy", which determine the fate of the Universe. Their nature is still under inv…
Cosmological constraints on unifying Dark Fluid models
A. Arbey
In the standard model of cosmology, dark matter and dark energy are presently the two main contributors to the total energy in the Universe. However, these two dark components are…
SN 2004aw: Confirming Diversity of Type Ic Supernovae
S. Taubenberger, A. Pastorello, P. A. Mazzali +24
Optical and near-infrared observations of the Type Ic supernova (SN) 2004aw are presented, obtained from day -3 to day +413 with respect to the B-band maximum. The photometric evol…
Dark Fluid: a complex scalar field to unify dark energy and dark matter
Alexandre Arbey
In this article, we examine a model which proposes a common explanation for the presence of additional attractive gravitational effects -- generally considered to be due to dark ma…
Unifying dark energy and dark matter with a scalar field
A. Arbey
The standard model of cosmology considers the existence of two components of unknown nature, ``dark matter'' and ``dark energy'', which determine the cosmological evolution. Their…
Is it possible to consider Dark Energy and Dark Matter as a same and unique Dark Fluid?
Alexandre Arbey
In the standard model of cosmology, the present evolution of the Universe is determined by the presence of two components of unknown nature. One of them is referenced as ``dark mat…
Galactic Halos of Fluid Dark Matter
Alexandre Arbey, Julien Lesgourgues, Pierre Salati
Dwarf spiral galaxies - and in particular the prototypical DDO 154 - are known to be completely dominated by an unseen component. The putative neutralinos - so far the favored expl…
Cosmological constraints on quintessential halos
Alexandre Arbey, Julien Lesgourgues, Pierre Salati
A complex scalar field has recently been suggested to bind galaxies and flatten the rotation curves of spirals. Its cosmological behavior is thoroughly investigated here. Such a fi…
Quintessential Haloes around Galaxies
Alexandre Arbey, Julien Lesgourgues, Pierre Salati
The nature of the dark matter that binds galaxies remains an open question. The favored candidate has been so far the neutralino. This massive species with evanescent interactions…
