The Extended Plane of the Local Supercluster

TL;DR

This paper presents evidence that certain cosmic structures like radio galaxies and clusters are more prevalent near the plane of the Local Supercluster, extending to distances of 200-400 Mpc.

Contribution

It provides updated observational evidence of the correlation between galaxy distributions and the Local Supercluster plane at large distances.

Findings

Radio galaxies and clusters are more common near the supercluster plane up to 200 Mpc.

Correlation with luminous galaxies at 400 Mpc suggests large-scale structure alignment.

The results challenge or confirm expectations from standard cosmology.

Abstract

An update of the evidence that radio galaxies and clusters of galaxies are more common than average near the plane of the de Vaucouleurs Local Supercluster shows that in the distance range 100 to 200Mpc objects whose positions are correlated with the plane of the Local Supercluster include galaxies that are exceptionally luminous at two microns, radio galaxies, and clusters of galaxies. There can be little doubt about this property of cosmic structure. I also argue for detection of this correlation for the galaxies at 400Mpc distance that are exceptionally luminous at two microns. It will be interesting to learn whether these results are expected in the standard cosmology.
