Diogo Castelão (FCUL)


In this talk I will present the work of testing, for the first time, a Unified Dark Matter-Energy model in the non-linear regime. Starting from a linear implementation, which includes a non linear effect named backreaction, in the Boltzmann code CLASS of a UDM Chaplygin Gas model tested against weak lensing, CMB, Sne IA and BAO, we focus on a simpler UDM model lagrangian to be implemented as a first test in an N-Body DM simulation code. I will present a spherical solution for the model as a test in the non-linear regime and the ongoing work in the implementation of the model in the N-Body code.
