Quasinormal Modes of Black Holes: Efficient and Highly Accurate Calculations with Recurrence-Based Methods
Kristian Benda, Jerzy Matyjasek
We discuss new recurrence-based methods for calculating the complex frequencies of the quasinormal modes of black holes. These methods are based on the Frobenius series solutions o…

Accurate quasinormal modes of the analogue black holes
Jerzy Matyjasek, Kristian Benda, Maja Stafińska
We study the quasinormal modes of the spherically-symmetric -dimensional analogue black hole, modeled by the ``draining bathtub'' fluid flow, and the -dimensional can…
