McVittie solution in f(T) gravity

General Relativity and Quantum Cosmology 2018-01-09 v3

Abstract

We show that McVittie geometry, which describes a black hole embedded in a FLRW universe, not only solves Einstein equations but also remains as a non-deformable solution of f(T) gravity. This search for GR solutions that survive in f(T) gravity is facilitated by a null tetrad approach. We also show that flat FLRW geometry is a consistent solution of f(T) dynamical equations not only for T=6H2T=-6H^{2} but also for T=0T=0, which could be a manifestation of the additional degrees of freedom involved in f(T) theories.
