Black Hole Persistence in Scalar Tensor Theories
Balkar Yildirim, Alan Albert Coley
We construct a perturbative scalar-tensor solution describing a central inhomogeneity embedded in an evolving cosmological background, with the aim of studying black hole persisten…

Black Hole Persistence in New General Relativity
Balkar Yildirim, Alan Albert Coley, Diego Fernando López
We investigate whether black holes can persist through the bounce with a minimal scale factor in a non-singular cosmology, whereby black holes from a previous contracting phase sur…

On non-vacuum black holes in new general relativity
D. F. López, A. A. Coley, B. Yildirim
New general relativity (NGR) is a torsion-based modification of general relativity whose Lagrangian depends on three free parameters, . A subset of the param…
