Scattering problems on rotating acoustic black holes |
Abstract _ |
Scattering problems on rotating acoustic black holes can be studied in the time domain by using numerical methods only. In order to obtain high quality results from simulations, tools developed by Numerical Relativists in the case of rotating Kerr black holes must be preferably adopted, i.e. constrained evolution schemes for strongly symmetric and non symmetric systems of hyperbolic PDEs and excision techniques in horizon penetrating coordinates. In this talk such a program is presented and analogies between astrophysical and acoustic black holes are discussed. |
