Lense-Thirring Acoustic Black Hole: Shadows and Light
Analysis
This paper introduces and analyzes the Lense-Thirring Acoustic Black Hole (LTABH), an analogue model for black holes. It investigates the spacetime geometry, shadow characteristics, and frame-dragging effects. The research is relevant for understanding black hole physics through analogue models in various physical systems.
Key Takeaways
- •Introduces the Lense-Thirring Acoustic Black Hole (LTABH) as an analogue model.
- •Analyzes the spacetime geometry and its dependence on acoustic and rotation parameters.
- •Investigates the shadows (acoustic and optical) and their dependence on the parameters.
- •Studies the frame-dragging effect and its behavior near the acoustic horizons.
- •Derives the deflection of light near the LTABH.
Reference
“The rotation parameter 'a' is more relevantly affecting the optical shadow radius (through a right shift), while the acoustic shadow retains its circular shape.”
