TY - JOUR TI - The isospectrality of asymptotic quasinormal modes of large Gauss-Bonnet d-dimensional black holes T2 - Nuclear Physics B VL - 993 AU - Moura, F. AU - Rodrigues, J. PY - 2023 SN - 0550-3213 DO - 10.1016/j.nuclphysb.2023.116255 UR - https://www.sciencedirect.com/science/article/pii/S0550321323001840?via%3Dihub AB - We compute the quasinormal frequencies of d-dimensional large spherically symmetric black holes with Gauss-Bonnet corrections in the highly damped regime. We solve perturbatively the master differential equation and we compute the monodromies of the master perturbation variable (analytically continued to the complex plane) in different contours, in order to obtain the quasinormal mode spectra. We consider tensorial, vectorial and scalar gravitational perturbations, obtaining the same frequencies for the three cases like in Einstein gravity. We also separately perform the same calculation for test scalar fields. ER -
