Abstract: Abstract Tidal effects in capped geometries computed in previous literature display no dynamics along internal (toroidal) directions. However, the dual CFT picture suggests otherwise. To resolve this tension, we consider a set of infalling null… read more here.

Abstract: Abstract We construct a family of non-supersymmetric extremal black holes and their horizonless microstate geometries in four dimensions. The black holes can have finite angular momentum and an arbitrary charge-to-mass ratio, unlike their supersymmetric cousins.… read more here.

Abstract: A bstractWe examine some recently-constructed families of asymptotically-AdS3 × S3$$ {\mathbb{S}}^3 $$ supergravity solutions that have the same charges and mass as supersymmetric D1-D5- P black holes, but that cap off smoothly with no horizon.… read more here.

DOI: 10.1088/1361-6382/aa7bfe
Abstract: It has been argued that supersymmetric microstate geometries are classically unstable. One argument for instability involves considering the motion of a massive particle near the ergosurface of such a spacetime. It is shown that the… read more here.

DOI: 10.1088/1361-6382/aaf133
Abstract: Ambi-polar metrics, defined so as to allow the signature to change from +4 to -4 across hypersurfaces, are a mainstay in the construction of BPS microstate geometries. This paper elucidates the cohomology of these spaces… read more here.
