Lecturer: Dr. Edoardo Carlesi Affiliation: Racah Institute of Physics, Hebrew University of Jerusalem Abstract: In the first part of this introductory talk I will describe my PhD work on N- Body/Hydro simulations of non standard cosmological models (of interacting dark matter-dark energy), which I did under the supervision of prof. Alexander Knebe at the Universidad Autonoma in Madrid. After reviewing the key features of these models as well as their numerical implementation into an N-Body code, I will discuss the main differences that could help distinguish these cosmologies from the standard LCDM paradigm. In the second part I will introduce my present research project, in which I am focusing on simulations of the local universe by means of constrained realizations of the initial conditions. I will discuss the techniques used as well as some preliminary results.
