Apparent horizons in Clifton-Mota-Barrow inhomogeneous universe [PDF]
Vincenzo Vitagliano, Valerio Faraoni, Thomas P. Sotiriou, Stefano LiberatiWe analyze the apparent horizon dynamics in the inhomogeneous Clifton-Mota-Barrow solution of Brans-Dicke theory. This solution models a central matter configuration embedded in a cosmological background. In certain regions of the parameter space we find solutions exhibiting dynamical creation or merging of two horizons.View original: http://arxiv.org/abs/1302.7150
