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…

Numerical Evidence for Non-Axisymmetric Gravitational "Hair" for Extremal Kerr Black Hole Spacetimes with Hyperboloidal Foliations
Som Dev Bishoyi, Subir Sabharwal, Gaurav Khanna
Various generalizations of the scalar, axisymmetric "horizon hair" for extremal black holes have recently appeared in the literature. In this paper, we propose an expression for a…

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…
