Cosmology and Fundamental Physics with the Euclid Satellite

Luca Amendola, +81 more
TL;DR: Euclid is a European Space Agency medium-class mission selected for launch in 2020 within the cosmic vision 2015-2025 program as discussed by the authors, which will explore the expansion history of the universe and the evolution of cosmic structures by measuring shapes and red-shift of galaxies as well as the distribution of clusters of galaxies over a large fraction of the sky.

Divergence free virtual elements for the stokes problem on polygonal meshes

TL;DR: This paper develops a new family of Virtual Elements for the Stokes problem on polygonal meshes that can guarantee that the final discrete velocity is pointwise divergence-free, and not only in a relaxed (projected) sense, as it happens for more standard elements.
Journal ArticleDOI

Virtual elements for the navier-stokes problem on polygonal meshes

TL;DR: In this paper, a family of virtual element methods for the Navier-Stokes equations is proposed and analyzed, which provide a discrete velocity field which is pointwise divergence-free.

Cosmology and Fundamental Physics with the Euclid Satellite

TL;DR: This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.
