Scalar Fields in Black Hole Spacetimes

Understand

The time-evolution of matter fields in black hole exterior spacetimes is a well-studied subject, spanning several decades of research.

• However, the behavior of fields in the black hole interior spacetime, has only relatively recently begun receiving some attention from the research community.
• In this paper, we numerically study the late-time evolution of scalar fields in both Schwarzschild and Kerr spacetimes, including the black hole interior.
• We recover the expected late-time power-law "tails" on the exterior (null infinity, time-like infinity and the horizon).
