Quasinormal Modes in Noncommutative Schwarzschild black holes

Abstract: We investigate the quasinormal modes of a massless scalar field in a Schwarzschild black hole, which is deformed due to noncommutative corrections. We present the deformed Schwarzschild black hole solution, which depends on the noncommutative parameter Θ, and we extract the master equation as a Schrödinger-like equation, giving the explicit expression of the effective potential which is modified due to the noncommutative corrections. We solve the master equation numerically and we find that the noncommutative … Show more

“…That seems to be the case in such spacetime independent of the logarithm term as in (2). Considering other modified theories of gravity in high dimensional spaces, such as that of [99,100] we point out two specific differences: in our thorough investigation the effective potential is always positive, not allowing for instabilities in the field evolution. The resulting scalar perturbation evolves consequently into a well-behaved tower of quasinormal modes.…”
