Abstract Supersymmetric, magnetically charged (and possibly accelerating) black holes in AdS4 that uplift on Sasaki-Einstein manifolds Y 7 to M-theory have a dual matrix model description. The matrix model in turn arises by localization of the 3d N $

Abstract We use equivariant localization to construct off-shell entropy functions for supersymmetric black holes in $$\mathcal{N}$$ = 2, D = 4 gauged supergravity coupled to matter. This allows one to compute the black hole entropy without solving th

Abstract We explain how equivariant localization may be applied to AdS/CFT to compute various BPS observables in gravity, such as central charges and conformal dimensions of chiral primary operators, without solving the supergravity equations. The ke

Abstract We construct supersymmetric AdS 3 solutions of D = 11 supergravity, dual to d = 2, N $$ \mathcal{N} $$ = (0, 2) SCFTs, that are associated with M5-branes wrapping two different four-dimensional orbifolds. In one case the orbifold is a spindl

Abstract In the context of holography, we analyse aspects of supersymmetric geometries based on two-dimensional orbifolds known as spindles. By analysing spin c spinors on a spindle with an azimuthal rotation symmetry we show that under rather genera

Abstract We construct supersymmetric AdS 5 × Σ solutions of D = 7 gauged supergravity, where Σ is a two-dimensional orbifold known as a spindle. These uplift on S 4 to solutions of D = 11 supergravity which have orbifold singularites. We argue tha

Abstract We construct families of supersymmetric AdS3 × Y 7 and AdS3 × Y 8 solutions to type IIB string theory and M-theory, respectively. Here Y 7 is an S 5 fibration over Σ, while Y 8 is an S 4 fibration over Σ g × Σ, where Σ g is a Riemann

Abstract While the study of bordered (pseudo-)holomorphic curves with boundary on Lagrangian submanifolds has a long history, a similar problem that involves (special) Lagrangian submanifolds with boundary on complex surfaces appears to be largely ov

Abstract We continue our study of a general class of N $$ \mathcal{N} $$ = 2 supersymmetric AdS 3 x Y 7 and AdS 2 x Y 9 solutions of type IIB and D = 11 supergravity, respectively. The geometry of the internal spaces is part of a general family of

Abstract We derive a simple formula for the action of any supersymmetric solution to minimal gauged supergravity in the AdS4/CFT3 correspondence. Such solutions are equipped with a supersymmetric Killing vector, and we show that the holographically r
