Formation and Evolution of Wakes in the Spacetime Generated by a Cosmic String in if/i(iR/i) Theory of Gravity

摘要

The formation and evolution of cosmic string wakes in the framework of a f(R) theory of gravity are investigated in this work. We consider a simple model in which baryonic matter flows past a cosmic string. We treat this problem in the Zel’dovich approximation. We compare our results with previous results obtained in the context of General Relativity and Scalar-Theories of Gravity.
