The enhançon mechanism removes a family of timelike singularities from certain supergravity spacetimes by forming a shell of branes on which the exterior geometry terminates. The problematic interior geometry is replaced by a new spacetime, which in... Read More about The enhançon and the consistency of excision..

Supersymmetric conical defects: towards a string theoretic description of black hole formation (2001)
Journal Article
Balasubramanian, V., de Boer, J., Keski-Vakkuri, E., & Ross, S. F. (2001). Supersymmetric conical defects: towards a string theoretic description of black hole formation. Physical Review D, Particles and fields, 64(6), https://doi.org/10.1103/physrevd.64.064011

Conical defects, or point particles, in AdS3 are one of the simplest nontrivial gravitating systems, and are particularly interesting because black holes can form from their collision. We embed the BPS conical defects of three dimensions into the N=4... Read More about Supersymmetric conical defects: towards a string theoretic description of black hole formation.
