Dynamical Black Rings with a Positive Cosmological Constant
arXiv:0904.4311 · doi:10.1103/PhysRevD.80.044012
Abstract
We construct dynamical black ring solutions in the five dimensional Einstein-Maxwell system with a positive cosmological constant and investigate the geometrical structure. The solutions describe the physical process such that a thin black ring at early time shrinks and changes into a single black hole as time increase. We also discuss the multi-black rings and the coalescence of them.
