| contents | <p>This version (v2.0) is a significant update to the previous submission [v1.0](https://doi.org/10.5281/zenodo.15568459), which proposed a rotating black hole solution within the Q-G Unified Field Theory. In this updated version, we refine the derivation of the rotating Kerr-type metric under the Q-G framework, incorporating corrections from the nonlinear coupling tensor Q_{μν}. </p> <p>Two major improvements are included:<br>1. A more precise expression for the shadow radius deviation δr_sh as a function of the black hole’s spin (a) and charge (Q), supported by updated contour visualizations.<br>2. A waveform-level comparison of quasinormal mode (QNM) ringdowns between Kerr–Newman and Q-G corrected models, highlighting observable phase shifts under EHT and gravitational wave detection schemes.</p> <p>The manuscript improves clarity, mathematical precision, and visualization quality, offering a more robust foundation for connecting Q-G theory to astrophysical observations.</p> |
