Rotating scalarized supermassive black holes

European Physical Journal C: Particles and Fields
In this study, we investigate rotating black hole solutions within a scalar-Gauss–Bonnet gravity framework that incorporates a squared Gauss–Bonnet term. By employing a quadratic–exponential coupling function between the scalar field and the Gauss–Bonnet

Signatures from the observed jet power and the radiative efficiency for rotating black holes in loop quantum gravity

European Physical Journal C: Particles and Fields
We investigate the radiative efficiency and jet power in the spacetime of a rotating black hole within the framework of loop quantum gravity (LQG), which includes an additional LQG parameter.

Weak gravity conjecture of charged-rotating-AdS black hole surrounded by quintessence and string cloud

Nuclear Physics B
A series of corrections to general relativity have recently been applied to find the relationship between entropy and extremality-bound black holes. This relationship has been investigated for many black holes, such as charged AdS, rotating, and massive ...

Luminosity of accretion disks around rotating regular black holes

European Physical Journal C: Particles and Fields
We study thin accretion disks in the gravitational field of a class of rotating regular black holes. Our objective is to determine the key parameters governing these accretion disks: the radius of the innermost stable circular orbit $$(r_{\textrm{ISCO}})$

Shadows of rotating black holes in effective quantum gravity

European Physical Journal C: Particles and Fields
Recently, two new spherically symmetric black hole models with covariance have been proposed in effective quantum gravity. Based on these models, we use the modified Newman–Janis algorithm to generate two rotating quantum-corrected black hole solutions ...
