Relativistic corrections to the rotation curves of disk galaxies

Astrophysics of Galaxies 2021-03-17 v2 General Relativity and Quantum Cosmology

Abstract

We present a method to investigate relativistic effects arising from large masses. The method is non-perturbative and employs a mean-field approximation and gravitational lensing. Using this method and a basic model of disk galaxy, we find that relativistic corrections to the rotation curves of disk galaxies are significant at large galactic radii. The model predicts a strong correlation between the inferred galactic dark mass and the galactic disk thickness, which we verified using two separate sets of observational data.
