A recent study has investigated energy extraction via the Comisso-Asenjo (CA) magnetic reconnection process near a rotating $\mathcal{N}=2,U(1)^2$ gauged supergravity black hole. This work focuses on how an independent set of parameters $(N_g, g, v, e)$, alongside the spin parameter $a$, influences the extracted energy ($\varepsilon_{\pm}$), efficiency ($\eta$), and extracted power ($\mathcal{P}_{CA}$). The aim is to identify optimal combinations that allow for higher energy extraction efficiency, even in cases of lower spin ($a \sim 0.39$), surpassing the efficiency of the extremal Kerr case ($a \sim 1$).

The researchers explored various parameter configurations, including extremal cases, and conducted an extensive comparison with the standard Kerr black hole. The influence of the orientation angle ($\xi$) and the magnetization parameter ($\sigma_0$) on both efficiency and power was also examined. The results demonstrate that the extremal Kerr black hole efficiency limit ($\eta > 1.495$) can be exceeded in these supergravity configurations. The methodology included using the statistical Kendall's Tau approach to identify key parameters acting as boosters or dampers in the energy extraction process.

Furthermore, the study reveals that the observable Lundquist number $S_{\rm obs}$ in rotating black hole spacetimes acquires an observer-dependent angular dependence through the lapse function ($\alpha$). This leads to deviations from the standard Sweet-Parker scaling when expressed in terms of observable quantities. These findings open new avenues for understanding energy extraction mechanisms in extreme astrophysical environments and their implications for black hole physics beyond the Standard Model.
