Dynamical and observational analysis of interacting models
F. E. M. Costa, A. O. Ribeiro, F. Roig
We investigate the dynamical behaviour of a general class of interacting models in the dark sector in which the phenomenological coupling between cold dark matter and dark energy i…

A possible analogy between the dynamics of a skydiver and a scalar field: cosmological consequences
F. E. M. Costa
The cosmological consequences of a slow rolling scalar field with constant kinetic term in analogy to the vertical movement of a skydiver after reaching terminal velocity are inves…
