Simple inhomogeneous cosmological (toy) models
Eddy G. Chirinos Isidro, Cristofher Zuñiga Vargas, Winfried Zimdahl
Based on the Lemaître-Tolman-Bondi (LTB) metric we consider two flat inhomogeneous big-bang models. We aim at clarifying, as far as possible analytically, basic features of the dyn…
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…
