Observations exploring the contemporary cosmic acceleration have sparked interest in dark energy models possessing equations of state with $wl\ensuremath{-}1$. We review how the cosmic expansion history of a Dvali-Gabadadze-Porrati (DGP) braneworld model with a standard brane cosmological constant can mimic that of ordinary 4D gravity with $wl\ensuremath{-}1$ phantom'' dark energy for observationally relevant redshifts. We reinterpret the effective phantom nature of the dark energy as arising…
