Query: Quasinormal modes of Einstein-Gauss-Bonnet-dilaton black holes   We study quasinormal modes of static Einstein-Gauss-Bonnet-dilaton black
holes. Both axial and polar perturbations are considered and studied from $l=0$
to $l=3$. We emphasize the difference in the spectrum between the Schwarzschild
solutions and dilatonic black holes. At large Gauss-Bonnet coupling constant a
small secondary branch of black holes is present, when the dilaton coupling is
sufficiently strong. The modes of the primary branch can differ from the
Schwarzschild modes up to $10\%$. The secondary branch is unstable and
possesses long-lived modes. We address the possible effects of these modes on
future observations of gravitational waves emitted during the ringdown phase of
astrophysical black holes.
