Query: Vectorial and spinorial perturbations in Galileon Black Holes:
  Quasinormal modes, quasiresonant modes and stability   In this work we have considered a model that includes the interaction of
gravity and matter fields with Galilean invariance (the so-called derivative
coupling) as well as some corresponding black hole type solutions. Quasinormal
perturbations of two kinds of matter fields have been computed by different
methods. The effect of the derivative coupling in the quasinormal spectrum has
been analyzed and evaluated.
