Query: Quasinormal Modes of Modified Gravity (MOG) Black Holes   The Quasinormal modes (QNMs) for gravitational and electromagnetic
perturbations are calculated in a Scalar-Tensor-Vector (Modified Gravity)
spacetime, which was initially proposed to obtain correct dynamics of galaxies
and galaxy clusters without the need for dark matter. It is found that for the
increasing model parameter $\alpha$, both the real and imaginary parts of the
QNMs decrease compared to those for a standard Schwarzschild black hole. On the
other hand, when taking into account the $1/(1+\alpha)$ mass re-scaling factor
present in MOG, Im($\omega$) matches almost identically that of GR, while
Re($\omega$) is higher. These results can be identified in the ringdown phase
of massive compact object mergers, and are thus timely in light of the recent
gravitational wave detections by LIGO.
