论文摘要
我们在爱丁顿启发的出生式重力中找到了一个精确的，旋转的带电的黑洞解决方案。为此，我们采用了最近开发的对应关系或{\ it映射}在修改的重力模型之间，作为与Ricci张量的度量标量构建的标量，并在公制的植入空间（基于RICCI的重力理论）和一般相对论中配制。这样，从Kerr-Newman解决方案开始，我们表明该映射为我们带来了埃德丁顿启发的Born-Infeld Gravity的轴对称解决方案，并与某些非线性电动力学模型相连。我们讨论了以这种方式获得的解决方案的最相关的物理特征，无论是在球形对称的极限和完全旋转方案中。此外，我们进一步详细阐述了这一重要技术进步的潜在影响，即通过对紧凑物体和重力波天文学的天体物理观测来更加接近修饰重力的预测。
We find an exact, rotating charged black hole solution within Eddington-inspired Born-Infeld gravity. To this end we employ a recently developed correspondence or {\it mapping} between modified gravity models built as scalars out of contractions of the metric with the Ricci tensor, and formulated in metric-affine spaces (Ricci-Based Gravity theories) and General Relativity. This way, starting from the Kerr-Newman solution, we show that this mapping bring us the axisymmetric solutions of Eddington-inspired Born-Infeld gravity coupled to a certain model of non-linear electrodynamics. We discuss the most relevant physical features of the solutions obtained this way, both in the spherically symmetric limit and in the fully rotating regime. Moreover, we further elaborate on the potential impact of this important technical progress for bringing closer the predictions of modified gravity with the astrophysical observations of compact objects and gravitational wave astronomy.
