# Gravitational anti-screening and binary galaxies

## TL;DR

This paper applies a gravitational anti-screening theory to binary galaxies, revealing a relationship between their velocity differences and individual rotations, aligning well with observational data for radial orbits.

## Contribution

It extends gravitational anti-screening theory to binary galaxies, deriving a probability function that matches observed velocity ratios for radial orbit pairs.

## Key findings

- Probability function for velocity ratio matches observations
- Relationship between line-of-sight velocity difference and galaxy rotation
- Agreement with observed binary galaxy dynamics

## Abstract

Previously, in Penner (2016a, 2016b), a theory of gravitational anti-screening was shown to lead naturally to the Baryonic Tully-Fisher Relationship. In addition, it was shown to agree with the observed rotational curve of the Galaxy, the observed features in the rotational curves of other spiral galaxies, with observations of the Coma cluster, and with a geometrically flat universe. In this paper the theory will now be applied to binary galaxies. It is shown that there is a relationship between the line-of-sight velocity difference of the pair and the individual rotational velocities of the galaxies. The resulting probability function for beta, defined as the ratio of the line-of-sight velocity difference to the rotational velocity of the larger galaxy of the pair, is in excellent agreement with the observations taken by multiple researchers for the case of the binaries being on radial orbits.
