We demonstrate how a five dimensional Godel universe appears as the core of resolved two-charge and three-charge over-rotating BMPV black holes. A smeared generalized supertube acts as a domain wall and removes regions of closed timelike curves by cutting off both the inside and outside solution before causality violations appear, effectively allowing the Godel universe and the over-rotating black hole to solve each other's causality problems. This mechanism suggests a novel form of holography… 

Supertube domain walls and elimination of closed timelike curves in string theory

We show that some novel physics of supertubes removes closed timelike curves from many supersymmetric spaces which naively suffer from this problem. The main claim is that supertubes naturally form

Chronology protection and the stringy exclusion principle

We construct a family of supersymmetric solutions to supergravity in three dimensions with a negative cosmological constant, that correspond to type IIB seven branes wrapped on an internal S3×T4.

Holographic dual of a time machine.

We apply the $AdS/CFT$ holography to the simplest possible eternal time machine solution in $AdS_3$ based on two conical defects moving around their center of mass along a circular orbit. Closed

One Ring to Rule Them All ... and in the Darkness Bind Them

We construct all eleven-dimensional, three-charge BPS solutions that preserve a fixed, standard set of supersymmetries. Our solutions include all BPS three-charge rotating black holes, black rings,

Gödel space from wrapped M2-branes

We show that M-theory admits a supersymmetric compactification to the Gödel universe of the form Gödel3×S2×CY3. We interpret this geometry as coming from the backreaction of M2-branes wrapping the S2

Supergravity microstates for BPS black holes and black rings

We demonstrate a solution generating technique, modulo some constraints, for a large class of smooth supergravity solutions with the same asymptotic charges as a five dimensional 3-charge BPS black

The Gödel-Schrödinger spacetime and stringy chronology protection

A bstractWe show that the null Melvin map applied to a rotational isometry of global anti-de Sitter space produces a spacetime with properties analogous to both the Gödel and Schrödinger geometries.

Evolution of Kerr superspinars due to accretion counterrotating thin discs

String theory predicts the existence of extremely compact objects spinning faster than Kerr black holes. The spacetime exterior to such superspinars is described by Kerr naked singularity geometry

Rotating black holes in a Gödel universe

We construct a five-dimensional, asymptotically Godel, three-charge black hole via dimensional reduction of an asymptotically plane wave, rotating D1-D5-brane solution of type-IIB supergravity. This

Three charge supertubes and black hole hair

We construct finite size, supersymmetric, tubular D-brane configurations with three charges, two angular momenta and several brane dipole moments. In type IIA string theory these are tubular

Gödel's universe in a Supertube shroud.

We demonstrate that certain supersymmetric Gödel-like universe solutions of supergravity are not solutions of string theory. This is achieved by realizing that supertubes are

Black holes in Godel-type universes with a cosmological constant

We discuss supersymmetric black holes embedded in a Godel-type universe with cosmo- logical constant in five dimensions. The spacetime is a fibration over a four-dimensional Kahler base manifold, and

Black holes in Gödel universes and pp waves.

We find exact solutions for rotating and nonrotating neutral black holes in the Gödel universe of five-dimensional minimal supergravity theory. We also describe the embedding of this solution in

The geodesics of the rotating extreme black hole in five spacetime dimensions found by Breckenridge, Myers, Peet and Vafa are Liouville integrable and may be integrated by additively separating the

Aspects of supertubes

We find supersymmetric solutions of the D4-brane Born-Infeld action describing D2 supertubes ending on an arbitrary curve inside a D4-brane. From the D4-brane point of view, these are dyonic strings.
