Extreme 5-dimensional black holes with SU(2)-symmetric horizons

Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1

We show that the near horizon geometry of 5-dimensional extreme (i.e., degenerate) stationary vacuum black holes, with or without cosmological constant, whose event horizons exhibi…

Deformations of the Kerr-(A)dS Near Horizon Geometry

Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1

We investigate deformations of the Kerr-(A)dS near horizon geometry and derive partial infinitesimal rigidity results for it. The proof comprises two parts. First, we follow the an…

Rigidity of quasi-Einstein metrics: The incompressible case

Eric Bahuaud, Sharmila Gunasekaran, Hari K Kunduri +1

As part of a programme to classify quasi-Einstein metrics on closed manifolds and near-horizon geometries of extreme black holes, we study such spaces when the vector fie…

Static near horizon geometries and rigidity of quasi-Einstein manifolds

Eric Bahuaud, Sharmila Gunasekaran, Hari K. Kunduri +1

Static vacuum near horizon geometries are solutions of a certain quasi-Einstein equation on a closed manifold , where is a Riemannian metric and is a closed 1-…

Slow decay of waves in gravitational solitons

Sharmila Gunasekaran, Hari K. Kunduri

We consider a family of globally stationary (horizonless), asymptotically flat solutions of five-dimensional supergravity. We prove that massless linear scalar waves in such solito…

Horizons as boundary conditions in spherical symmetry

Sharmila Gunasekaran, Ivan Booth

We initiate the development of a horizon-based initial (or rather final) value formalism to describe the geometry and physics of the near-horizon spacetime: data specified on the h…

Soliton mechanics

Sharmila Gunasekaran, Uzair Hussain, Hari K. Kunduri

The domain of outer communication of five-dimensional asymptotically flat stationary spacetimes may possess non-trivial 2-cycles (bubbles). Spacetimes containing such 2-cycles can…

Extended phase space thermodynamics for charged and rotating black holes and Born-Infeld vacuum polarization

Sharmila Gunasekaran, David Kubiznak, Robert B. Mann

We investigate the critical behaviour of charged and rotating AdS black holes in d spacetime dimensions, including effects from non-linear electrodynamics via the Born-Infeld actio…
