Kerr black holes with scalar hair.
We present a family of solutions of Einstein's gravity minimally coupled to a complex, massive scalar field, describing asymptotically flat, spinning black holes with scalar hair and a regularExpand
Testing general relativity with present and future astrophysical observations
One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests probe the theoryExpand
Boson stars with negative cosmological constant
Abstract We consider boson star solutions in a D-dimensional, asymptotically anti-de Sitter spacetime and investigate the influence of the cosmological term on their properties. We find that for D>3Expand
Spontaneous Scalarization of Charged Black Holes.
Numerical simulations in spherical symmetry show, dynamically, that Reissner-Nordström (RN) BHs evolve into a perturbatively stable scalarized BH, and speculate on a possible dynamical role of these nonspherical scalarization BHS. Expand
Construction and physical properties of Kerr black holes with scalar hair
Kerr black holes with scalar hair are solutions of the Einstein-Klein-Gordon field equations describing regular (on and outside an event horizon), asymptotically flat black holes with scalar hairExpand
Nut Charged Space-times and Closed Timelike Curves on the Boundary
We consider higher dimensional generalizations of the four dimensional topological Taub-NUT-AdS solutions, where the angular spheres (θ,) are replaced by planes and hyperboloids. The thermodynamicsExpand
Lensing and dynamics of ultracompact bosonic stars
Spherically symmetric bosonic stars are one of the few examples of gravitating solitons that are known to form dynamically, via a classical process of (incomplete) gravitational collapse. AsExpand
Traversable Wormholes in Einstein-Dirac-Maxwell Theory.
It is shown the existence of spherically symmetric asymptotically flat configurations which are free of singularities, representing localized states in Einstein-Dirac-Maxwell theory, and satisfy a generalized Smarr relation. Expand
New nonuniform black string solutions
We present nonuniform vacuum black strings in five and six spacetime dimensions. The conserved charges and the action of these solutions are computed by employing a quasilocal formalism. We findExpand
Black objects in the Einstein-Gauss-Bonnet theory with negative cosmological constant and the boundary counterterm method
We propose to compute the action and global charges of the asymptotically anti-de Sitter solutions in Einstein-Gauss-Bonnet theory by adding boundary counterterms to the gravitational action. TheExpand
