"Quartessence models: A unified point of view"

H. Velten

Quartessence models are a phenomenological way to explain dark energy and dark mater as a single fluid. The two main candidates for this scenary are the Chaplygin Gas and the Bulk Viscous Fluid, which is a fluid with dissipative correction in its equation of state. We discuss the background and perturbative dynamics of these models and show recent results obtained from observational data.
