Gravitational Lensing and Shadow of a Black Hole in Bumblebee Gravity
Analysis
This paper explores the strong gravitational lensing and shadow properties of a black hole within the framework of bumblebee gravity, which incorporates a global monopole charge and Lorentz symmetry breaking. The study aims to identify observational signatures that could potentially validate or refute bumblebee gravity in the strong-field regime by analyzing how these parameters affect lensing observables and shadow morphology. This is significant because it provides a way to test alternative theories of gravity using astrophysical observations.
Key Takeaways
- •Investigates strong gravitational lensing and shadow properties of a black hole in bumblebee gravity.
