Abstract
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 late-time behavior of the field as recorded by a static observer is given by where depends weakly on time. This result is carried over to the case of a Kerr black hole. In particular, it is found that the power-law index of depends on neither the multipole mode nor on the spin rate of the black hole In all black hole spacetimes, massive scalar fields have the same late-time behavior irrespective of their initial data (i.e., angular distribution). Their late-time behavior is universal.
