New asymptotically flat gravitational instanton
Edward Teo
A new two-parameter asymptotically flat (AF) toric gravitational instanton is identified as a special case of the Euclidean double Kerr-NUT solution, by imposing certain symmetry a…
Parametric solutions to the Kerr separatrix
Tammy Ng, Edward Teo
The Kerr separatrix is a boundary in parameter space that separates bound orbits from plunging orbits in the Kerr black hole space-time. Recently, Stein and Warburton found a polyn…
Multi-centered rotating black holes in Kaluza-Klein theory
Edward Teo, Thomas Wan
The most general charged and rotating black hole in Kaluza-Klein theory is known to be described by the Rasheed-Larsen solution. When the under-rotating extremal limit of this solu…
Spherical orbits around a Kerr black hole
Edward Teo
A special class of orbits known to exist around a Kerr black hole are spherical orbits -- orbits with constant coordinate radii that are not necessarily confined to the equatorial…
Rotating and accelerating black holes with cosmological constant
Yu Chen, Cheryl Ng, Edward Teo
We propose a new form of the rotating C-metric with cosmological constant, which generalises the form found by Hong and Teo for the Ricci-flat case. This solution describes the ent…
Black holes with bottle-shaped horizons
Yu Chen, Edward Teo
We present a new class of four-dimensional AdS black holes with non-compact event horizons of finite area. The event horizons are topologically spheres with one puncture, with the…
