Regular Rotating MOG Dark Compact Object

TL;DR

This paper introduces a regular rotating modified gravity compact object that generalizes the Kerr black hole, exploring its properties and physical implications depending on a key parameter, and highlighting conditions for regularity versus black hole behavior.

Contribution

The paper derives a new regular rotating MOG compact object that reduces to Kerr black hole for specific parameter values, extending the understanding of alternative gravity solutions.

Findings

The object is regular everywhere for alpha > 0.674.

It behaves as a Kerr-MOG black hole for alpha < 0.674.

Physical consequences depend on the value of alpha.

Abstract

A regular rotating MOG (modified gravity) compact object is derived that reduces to the Kerr black hole when the parameter $\alpha=0$. Physical consequences of the dark compact object, which is regular everywhere in spacetime for $\alpha > \alpha_{\rm crit}=0.674$ and is a rotating Kerr-MOG black hole for $\alpha < \alpha_{\rm crit}$ are investigated.
