Closed Timelike Curves from a Vacuum Traveling Wave
Semin Xavier
We construct an exact vacuum spacetime that develops closed timelike curves from regular, asymptotically flat initial data respecting the weak, dominant, and strong energy conditio…
Infinitely degenerate slowly rotating solutions in gravity
Alan Sunny, Semin Xavier, S. Shankaranarayanan
This work tests the no-hair conjecture in gravity models. No-hair conjecture asserts that all black holes in General Relativity coupled to any matter must be Kerr-Newman typ…
The dominating mode of two competing massive modes of quadratic gravity
Avijit Chowdhury, Semin Xavier, S. Shankaranarayanan
Over the last two decades, motivations for modified gravity have emerged from both theoretical and observational levels. and Chern-Simons gravity have received more attentio…
An exact model for evaporating primordial black holes in cosmological space-time
Semin Xavier, Alan Sunny, S. Shankaranarayanan
Primordial black holes (PBHs) in the mass range are considered as possible dark matter candidates as they are not subject to big-bang nucleosynthesis c…
Infinitely degenerate exact Ricci-flat solutions in f(R) gravity
Semin Xavier, Jose Mathew, S. Shankaranarayanan
We obtain an infinite number of exact static, Ricci-flat spherically symmetric vacuum solutions for a class of f(R) theories of gravity. We analytically derive two exact vacuum bla…
