Voids, dark energy and tidal forces...?

Click For Summary
SUMMARY

The discussion centers on the relationship between dark energy and the properties of cosmic voids, specifically their ellipticity and the influence of tidal forces. The authors of the referenced papers establish that dark energy contributes to the increased ellipticity of voids, indicating that as dark energy density rises, the tidal forces within these voids also intensify. This correlation suggests that the accelerated expansion of the universe has a significant impact on the structural dynamics of voids.

PREREQUISITES
  • Understanding of dark energy concepts in cosmology
  • Familiarity with cosmic voids and their properties
  • Knowledge of tidal forces in astrophysics
  • Basic grasp of ellipticity in geometric contexts
NEXT STEPS
  • Research the implications of dark energy on cosmic structure formation
  • Explore the mathematical modeling of void ellipticity
  • Investigate the role of tidal forces in cosmic evolution
  • Examine recent studies on the effects of dark energy density variations
USEFUL FOR

Astronomers, cosmologists, and astrophysicists interested in the dynamics of cosmic structures and the implications of dark energy on the universe's evolution.

TL;DR
Voids, dark energy and tidal forces...?
I would like to ask you some questions I have about some interesting work I was reading (https://arxiv.org/abs/1205.4238 & https://academic.oup.com/mnras/article/527/4/11962/7457744) where the authors analysed the effects of dark energy in the shape and evolution of voids

Apparently, they established a relation between dark energy, voids' ellipticity and tidal forces. I have a question about this, since it was not entirely clear to me:

Does it mean that dark energy (or the accelerated expansion of the universe) contributes to increase the ellipticity of voids? Then, does dark energy increase the tidal forces of the void (so that a greater dark energy density in the universe would result in more intense tidal forces in the void)?
