Structure formation in a nonlocally modified gravity model
  We study a nonlocally modified gravity model proposed by Deser and Woodard
which gives an explanation for current cosmic acceleration. By deriving and
solving the equations governing the evolution of the structure in the Universe,
we show that this model predicts a pattern of growth that differs from standard
general relativity (+dark energy) at the 10-30% level. These differences will
be easily probed by the next generation of galaxy surveys, so the model should
be tested shortly.
