Gravitomagnetism in the Lewis cylindrical metrics
- PhysicsClassical and Quantum Gravity
- 2020
The Lewis solutions describe the exterior gravitational field produced by infinitely long rotating cylinders, and are useful models for global gravitational effects. When the metric parameters are…
Superboost transitions, refraction memory and super-Lorentz charge algebra
- PhysicsJournal of High Energy Physics
- 2018
A bstractWe derive a closed-form expression of the orbit of Minkowski spacetime under arbitrary Diff(S2) super-Lorentz transformations and supertranslations. Such vacua are labelled by the…
On the first G1 stiff fluid spike solution in General Relativity
- Physics
- 2016
Using the Geroch transformation we obtain the first example of an exact stiff fluid spike solution to the Einstein field equations in a closed form exhibiting a spacelike G1 group of symmetries…
The double copy: Bremsstrahlung and accelerating black holes
- Physics
- 2016
A bstractAdvances in our understanding of perturbation theory suggest the existence of a correspondence between classical general relativity and Yang-Mills theory. A concrete example of this…
On the integrability of Einstein–Maxwell–(A)dS gravity in the presence of Killing vectors
- Mathematics, Physics
- 2015
We study symmetry and integrability properties of four-dimensional Einstein–Maxwell gravity with a nonvanishing cosmological constant in the presence of Killing vectors. First of all, we consider…
Geometric horizons in the Kastor-Traschen multi-black-hole solutions
- MathematicsPhysical Review D
- 2018
We investigate the existence of invariantly defined quasi-local hypersurfaces in the Kastor-Traschen solution containing $N$ charge-equal-to-mass black holes. These hypersurfaces are characterized by…
Local properties and global structure of McVittie spacetimes with non-flat Friedmann–Lemaître–Robertson–Walker backgrounds
- Mathematics, Physics
- 2017
McVittie spacetimes embed the vacuum Schwarzschild(-(anti) de Sitter) spacetime in an isotropic, Friedmann–Lemaître–Robertson–Walker (FLRW) background universe. The global structure of such…
Black hole chemistry: thermodynamics with Lambda
- Physics
- 2016
We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic…
The NUTs and Bolts of squashed holography
- Physics
- 2016
A bstractWe evaluate the partition function of the free O(N ) model on a two-parameter family of squashed three spheres. We also find new solutions of general relativity with negative cosmological…
Numerical solutions of Einstein's equations for cosmological spacetimes with spatial topology S 3 and symmetry group U(1)
- Physics, Mathematics
- 2016
We apply a single patch pseudo-spectral scheme based on integer spin-weighted spherical harmonics presented in [1, 2] to Einstein’s equations. The particular hyperbolic reduction of Einstein’s…
