We study the observational constraints on the Phantom Crossing DGP model .
We demonstrate that the crossing of the phantom divide does not occur within the framework of the original Dvali-Gabadadze-Porrati ( DGP ) model or the DGP model developed by Dvali and Turner .
By extending their model in the framework of an extra dimension scenario , we study a model that realizes crossing of the phantom divide .
We investigate the cosmological constraints obtained from the recent observational data of Type Ia Supernovae , Cosmic Microwave Background anisotropies , and Baryon Acoustic Oscillations .
The best fit values of the parameters with 1 \sigma ( 68 % ) errors for the Phantom Crossing DGP model are \Omega _ { m, 0 } = 0.27 ^ { +0.02 } _ { -0.02 } , \beta = 0.54 ^ { +0.24 } _ { -0.30 } .
We find that the Phantom Crossing DGP model is more compatible with the observations than the original DGP model or the DGP model developed by Dvali and Turner .
Our model can realize late-time acceleration of the universe , similar to that of \Lambda CDM model , without dark energy due to the effect of DGP gravity .
In our model , crossing of the phantom divide occurs at a redshift of z \sim 0.2 .
