Query: Black hole quasinormal modes and isospectrality in Deser-Woodard
  nonlocal gravity   We investigate the gravitational perturbations of the Schwarzschild black
hole in the nonlocal gravity model recently proposed by Deser and Woodard
(DW-II). The analysis is performed in the localized version in which the
nonlocal corrections are represented by some auxiliary scalar fields. We find
that the nonlocal corrections do not affect the axial gravitational
perturbations, and hence the axial modes are completely identical to those in
General Relativity (GR). However, the polar modes get different from their GR
counterparts when the scalar fields are excited at the background level. In
such a case the polar modes are sourced by an additional massless scalar mode
and, as a result, the isospectrality between the axial and the polar modes
breaks down. We also perform a similar analysis for the predecessor of this
model (DW-I) and arrive at the same conclusion for it.
