Plasma effects on gravitational lensing and shadow observables of a Kerr-like black hole in a dark matter halo
Connor McMillin, Zhichen Guan, Owen Gartlan +3
Plasma surrounding a black hole modifies light propagation and can alter the observed shadow, potentially affecting the interpretation of Event Horizon Telescope data. We study the…
Energy Extraction via Magnetic Reconnection from a Rotating Dyonic Black Hole in Gauged Supergravity
Raid M Suleiman, Shanshan Rodriguez, Dominic O. Chang +1
We study energy extraction via magnetic reconnection from a rotating dyonic black hole in four-dimensional , gauged supergravity. Using the Comisso-Asenjo mechanism i…
Superradiant Suppression of Non-minimally Coupled Scalar fields for a Rotating Charged dS Black Hole in Conformal Weyl Gravity
Owen Gartlan, Jacob March, Leo Rodriguez +2
In this study, we present an analytical investigation of the superradiant scattering of a massive charged conformally coupled scalar field in rotating charged black hol…
Geometrodynamics of a 2D Curved Surface due to a Constrained Quantum Particle via its Gravitational Dual: Analytical Model Calculations
Shanshan Rodriguez, Leo Rodriguez, Zhenzhong Xing +2
We provide a unique and novel extension of da Costa's calculation of a quantum mechanically constrained particle. This is achieved by analyzing the perturbative back reaction of th…
Energy extraction through magnetic reconnection from a Kerr-Newman black hole in perfect fluid dark matter
Shanshan Rodriguez, Alex Sidler, Leo Rodriguez +1
In this work, we provide a thorough analysis of energy extraction via magnetic reconnection, a novel mechanism recently proposed by Comisso and Asenjo, for a Kerr-Newman black hole…
