Source-Driven Tails in Kerr Spacetime: Nonlinear effects in Late-Time Behavior
Som Dev Bishoyi, Subir Sabharwal, Gaurav Khanna
We present the long-duration time-domain simulations of scalar-field tails in Kerr spacetimes driven by \emph{outgoing} multipolar sources. Extending the recent work in the literat…

Universality of massive scalar field late-time tails in black-hole spacetimes
Lior M. Burko, G. Khanna
The late-time tails of a massive scalar field in the spacetime of black holes are studied numerically. Previous analytical results for a Schwarzschild black hole are confirmed: The…
