Indefinitely flat rotation curves from Mpc sized charged cocoons

TL;DR

This paper proposes a novel explanation for flat galaxy rotation curves at Mpc scales using charged cocoons of electrostatic and vacuum energy, extending the model to early universe conditions and predicting observable effects in the CMB spectrum.

Contribution

It introduces the concept of charged cocoons as a new form of dark matter, providing an analytic solution that explains flat rotation curves and predicts CMB features.

Findings

Rotation curves remain flat up to Mpc scales.

Charged cocoons induce specific CMB spectrum peaks.

Model extends to early universe conditions.

Abstract

Weak lensing exhibits that rotation curves of isolated galaxies remain flat up to Mpc scale (Mistele et al, 2024). Recently we proposed that dark matter is a combination of electrostatic and vacuum energy in standard physics. In this theory, isolated galaxies may be embedded in ``charged cocoons'', spheres with $\pm 1/r^2$ charge density. The related circular rotation curves decay at the Mpc scale. The analytic solution is extended to the early Universe. A peak in the cosmic microwave background spectrum is expected at the arcsec scale. The induced nanometer size of the cocoons at the Big Bang makes the initial state inhomogeneous.
