Roland Triay (CPT), Henri-Hugues Fliche (LMMT)
TL;DR
This paper investigates how the cosmological constant influences the growth of cosmic voids using a Newtonian approach extended to Friedmann-Lemaître models, highlighting its significant effect on void evolution.
Contribution
It introduces a new Newtonian framework extended to Friedmann-Lemaître models to analyze the impact of the cosmological constant on void growth.
Findings
Cosmological constant significantly promotes void growth.
Extended Newtonian approach applicable to Friedmann-Lemaître models.
Provides insights into void evolution in the universe.
Abstract
We show that the cosmological constant favours significantly the growth of voids in the universe. This dynamical effect is investigated within a newtonian approach with an extension to Friedmann-Lema\^{\i}tre model.
