Topological Stars and Black Holes
Ibrahima Bah, Pierre Heidmann
We study smooth bubble spacetimes in five-dimensional Einstein-Maxwell theory that resemble four-dimensional magnetic black holes upon Kaluza-Klein reduction. We denote them as Top…

The Great Escape: Tunneling out of Microstate Geometries
Iosif Bena, Felicity Eperon, Pierre Heidmann +1
We compute the quasi-normal frequencies of scalars in asymptotically-flat microstate geometries that have the same charge as a D1-D5-P black hole, but whose long BTZ-like throat en…
