Cosmic voids and the kinetic analysis. V. Hubble tension, the cosmological constant and aperiodic filaments

TL;DR

This paper uses kinetic theory to explain local cosmic structures, the Hubble tension, and the emergence of aperiodic filaments and voids, highlighting the role of the cosmological constant and intrinsic damping mechanisms.

Contribution

It introduces a kinetic approach to cosmic structure formation, linking the Hubble tension and aperiodic filamentary structures to fundamental physical processes.

Findings

Hubble tension explained by local and global flow differences

Aperiodic structures arise naturally from kinetic damping effects

Predicted damping of aperiodicity observable at larger filament scales

Abstract

We study the appearance and specific properties of the structures in the local Universe by means of the Vlasov kinetic technique. We consider the role of the cosmological constant in local structure formation via the theorem on the general function that satisfies the identity of the gravity of the sphere and of the point mass. Then, the Hubble tension is naturally explained as a result of two flows, a local and a global one, with non-coinciding Hubble parameters. The linearized Vlasov-Poisson equation with the cosmological term is shown to lead to van Kampen's waves, Landau damping, and then to aperiodic structures. Aperiodicity thereby emerges as a intrinsic feature of the filamentary and void structure of the local Universe, and reveals the self-consistent field mechanism of its formation. The damping of the aperiodicity is then predicted and can be observationally traced upon the increase in the scale of the filaments.
