Quasinormal modes of rotating black holes in shift-symmetric Einstein-scalar-Gauss-Bonnet theory
Fech Scen Khoo, Jose Luis Blázquez-Salcedo, Burkhard Kleihaus +1
We employ a recently developed spectral method to obtain the spectrum of quasinormal modes of rapidly rotating black holes in alternative theories of gravity and apply it to the bl…

Quasinormal mode spectrum of rotating black holes in Einstein-Gauss-Bonnet-dilaton theory
Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Burkhard Kleihaus +1
Quasinormal modes are excited during the ringdown phase of black holes after merger. Determination of quasinormal modes of rapidly rotating black holes in alternative theories of g…

Quasinormal modes of rapidly rotating Einstein-Gauss-Bonnet-dilaton black holes
Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Burkhard Kleihaus +1
Quasinormal modes of rapidly rotating black holes are crucial in understanding the ringdown phase after a merger. While for Kerr black holes these modes have been known for a long…
