Contribution

It provides a concise overview of recent theoretical approaches and topics related to large scale structures, including the Effective Field Theory and relativistic considerations.

Findings

Dark matter perturbations evolve from inflation to today.

Relativistic effects are significant in non-linear structure formation.

Dark energy influences large scale structure dynamics.

Abstract

We briefly review some selected topics gravitating around large scale structures. We derive from inflation the evolution of dark matter perturbations. The stress is put on the non-linear regime of structures formation, with a particular emphasis on relativistic effects, the Effective Field Theory approach, the role of dark energy and the possibility of inhomogeneous universes.
