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 …

The idea of stable, localized bundles of energy has strong appeal as a model for particles. In
the 1950s, John Wheeler envisioned such bundles as smooth configurations of …

The wide applications of higher dimensional gravity and gauge/gravity duality have fuelled
the search for new stationary solutions of the Einstein equation (possibly coupled to matter) …

A bstract Black holes in anti-de Sitter (AdS) backgrounds play a pivotal role in the
gauge/gravity duality where they determine, among other things, the approach to equilibrium …

Despite the recent evidence that anti-de Sitter (AdS) spacetime is nonlinearly unstable, we
argue that many asymptotically AdS solutions are nonlinearly stable. This includes geons …

We construct boson stars in global anti–de Sitter (AdS) space and study their stability. Linear
perturbation results suggest that the ground state along with the first three excited state …

A bstract We revisit the issues of non-linear AdS stability, its relation to growing (secular)
terms in naıve perturbation theory around the AdS background, and the need and possible …

We construct time-periodic solutions for a system of a self-gravitating massless scalar field,
with a negative cosmological constant, in d+ 1 spacetime dimensions at spherical symmetry …

Recently, studies of the gravitational collapse of a scalar field within spherically symmetric
anti–de Sitter (AdS) spacetimes presented by Bizon and Rostroworoski [Phys. Rev. Lett …

A bstract We continue our analytic investigations of non-linear spherically symmetric
perturbations around the anti-de Sitter background in gravity-scalar field systems, and focus …
