The holographic Ricci dark energy and its possible doomsdays
Moulay-Hicham Belkacemi, Mariam Bouhmadi-Lopez, Ahmed Errahmani +1
It is well known that the holographic Ricci dark energy can induce some future doomsdays in the evolution of the universe. Here we analyse the possible avoidance of those doomsdays…
Cosmography of f(R) - brane cosmology
Mariam Bouhmadi-Lopez, Salvatore Capozziello, Vincenzo F. Cardone
Cosmography is a useful tool to constrain cosmological models, in particular dark energy models. In the case of modified theories of gravity, where the equations of motion are gene…
On the quantum fate of singularities in a dark-energy dominated universe
Mariam Bouhmadi-Lopez, Claus Kiefer, Barbara Sandhoefer +1
Classical models for dark energy can exhibit a variety of singularities, many of which occur for scale factors much bigger than the Planck length. We address here the issue whether…
Phantom-like behaviour in a brane-world model with curvature effects
Mariam Bouhmadi-Lopez, Paulo Vargas Moniz
Recent observational evidence seems to allow the possibility that our universe may currently be under a dark energy effect of a phantom nature. A suitable effective phantom fluid b…
On the generalised Chaplygin gas: worse than a big rip or quieter than a sudden singularity?
Mariam Bouhmadi-Lopez, Pedro F. Gonzalez-Diaz, Prado Martin-Moruno
Although it has been believed that the models with generalised Chaplygin gas do not contain singularities, in a previous work we have studied how a big freeze could take place in s…
Worse than a big rip?
Mariam Bouhmadi-Lopez, Pedro F. Gonzalez-Diaz, Prado Martin-Moruno
We show that a generalised phantom Chaplygin gas can present a future singularity in a finite future cosmic time. Unlike the big rip singularity, this singularity happens for a fin…
