Dark energy domination in the local flow of giant galaxies

TL;DR

This paper investigates the local expansion flow of giant galaxies within 10 Mpc, demonstrating that its dynamics are primarily influenced by local dark energy, based on recent Hubble Space Telescope data.

Contribution

It provides new evidence that local dark energy dominates the dynamics of the galaxy flow within the local universe.

Findings

Dark energy dominates the local galaxy flow dynamics

Recent Hubble data supports dark energy influence

Flow structure consistent with dark energy effects

Abstract

A dozen most luminous galaxies at distances up to 10 Mpc from the Local Group are moving away from the group forming the local expansion flow of giants. We use recent Hubble Space Telescope data on the local giants and their numerous fainter companions to study the dynamical structure and evolutionary trends of the flow. It is demonstrated that the dynamics of the flow is dominated by local dark energy. Keywords: Galaxies, groups and clusters of galaxies; local flows of galaxies; dark energy.
