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…
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…
