Freely acting orbifolds of type IIB string theory on
George Gkountoumis, Chris Hull, Koen Stemerdink +1
We study freely acting orbifolds of type IIB string theory on that spontaneously break supersymmetry from to or 0 in five dimensions. We f…
Universal spindles: D2's on and M5's on
Christopher Couzens, Koen Stemerdink
We study the uplift of a 4d black hole in 4d Einstein--Maxwell supergravity with a spindle horizon to massive type IIA and 11d supergravity on . The solutio…
M2-branes on Discs and Multi-Charged Spindles
Christopher Couzens, Koen Stemerdink, Damian van de Heisteeg
We study supersymmetric AdS solutions of 11d supergravity where is an fibration over a Riemann surface equipped with a metric of non-constant curvature. W…
The Near-Horizon Geometry of Supersymmetric Rotating AdS Black Holes in M-theory
Christopher Couzens, Eric Marcus, Koen Stemerdink +1
We classify the necessary and sufficient conditions to obtain the near-horizon geometry of extremal supersymmetric rotating black holes embedded in 11d supergravity. Such rotating…
Black holes in string theory with duality twists
Chris Hull, Eric Marcus, Koen Stemerdink +1
We consider 5D supersymmetric black holes in string theory compactifications that partially break supersymmetry. We compactify type IIB on and then further compactify on a ci…
