Non-vacuum black holes in new general relativity

Abstract: New general relativity (NGR) possesses a region in the ((c_{a},c_{v},c_{t}))-parameter space corresponding to physically acceptable models. However, when solving the field equations for vacuum and non--vacuum static and spherically symmetric configurations under the assumption of the existence of a local black hole horizon, we find that the mere existence of such solutions imposes algebraic constraints that fix the parameters to values associated with known pathological models. As a consequence, we conclude that NGR is unable to describe physically meaningful non-trivial black holes.
