Constraining LTB models with JLA supernovae and BAO
C. Z. Vargas, F. T. Falciano, R. R. R. Reis
In the present work we constrain three different profiles of a Lemaître-Tolman-Bondi model using supernovae type Ia and baryon acoustic oscillation data. We improve common practice…
Interacting dark energy and transient accelerated expansion
W. Zimdahl, C. Z. Vargas, W. S. Hipólito-Ricaldi
We argue that interactions in the dark sector may have a crucial impact on the cosmological dynamics. In particular, the future cosmic evolution may be very different from that pre…
Perturbations for transient acceleration
Cristofher Zuñiga Vargas, Wiliam S. Hipólito-Ricaldi, Winfried Zimdahl
According to the standard CDM model, the accelerated expansion of the Universe will go on forever. Motivated by recent observational results, we explore the possibility of a fin…
