Exact -cosmological model coming from the request of the existence of a Noether symmetry
S. Capozziello, P. Martin-Moruno, C. Rubano
We present an -cosmological model with an exact analytic solution, coming from the request of the existence of a Noether symmetry, which is able to describe a dust-dominated…
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…
