Spacetime Structure of a Regular Accelerating Black Hole Pair in General Relativity
M. M. Akbar, C. P. Brewer, S. M. Modumudi
We revisit the one-parameter generalization of the C-metric derived by Ernst, which solves the vacuum Einstein equations. Resolving conflicting claims in the literature, we determi…

Near-Horizon Symmetries of Local Black Holes in General Relativity
M. M. Akbar, S. M. Modumudi
We analyze the near-horizon symmetries of static, axisymmetric, four-dimensional black holes with spherical and toroidal horizon topologies in vacuum general relativity. These blac…

On the Effects of Non-metricity in an Averaged Universe
Anish Agashe, Sai Madhav Modumudi
In the covariant averaging scheme of macroscopic gravity, the process of averaging breaks the metricity of geometry. We reinterpret the back-reaction within macroscopic gravity in…
