A critical dimension for the stability of perfect fluid spheres of radiation
John Hammersley
An analysis of radiating perfect fluid models with asymptotically AdS boundary conditions is presented. Such scenarios consist of a spherical gas of radiation (a "star") localised…

Numerical metric extraction in AdS/CFT
John Hammersley
An iterative method for recovering the bulk information in asymptotically AdS spacetimes is presented. We consider zero energy spacelike geodesics and their relation to the entangl…

Extracting the bulk metric from boundary information in asymptotically AdS spacetimes
John Hammersley
We use geodesic probes to recover the entire bulk metric in certain asymptotically AdS spacetimes. Given a spectrum of null geodesic endpoints on the boundary, we describe two rema…
