Challenges to the DGP Model from Horizon-Scale Growth and Geometry

Fang, Wenjuan, Wang, Sheng, Hu, Wayne et al.

Understand

We conduct a Markov Chain Monte Carlo study of the Dvali-Gabadadze-Porrati (DGP) self-accelerating braneworld scenario given the cosmic microwave background (CMB) anisotropy, supernovae and Hubble constant data by implementing an effective dark energy prescription for modified gravity into a standard Einstein-Boltzmann code.

We find no way to alleviate the tension between distance measures and horizon scale growth in this model.
Growth alterations due to perturbations propagating into the bulk appear as excess CMB anisotropy at the lowest multipoles.
In a flat cosmology, the maximum likelihood DGP model is nominally a 5.3 sigma poorer fit than Lambda CDM.
