Undulating Conformal Boundaries in 3D Gravity
Weam Abou Hamdan, Chawakorn Maneerat
We consider three-dimensional Einstein gravity in Euclidean signature with a finite boundary of torus topology endowed with an induced metric of fixed conformal class and a constan…
The Stretched Horizon Limit
Dionysios Anninos, Damián A. Galante, Silvia Georgescu +2
We consider four-dimensional general relativity with a positive cosmological constant, , in the presence of a boundary, , of finite spatial size. The boundary is located near…
Conformal boundaries near extremal black holes
Damián A. Galante, Chawakorn Maneerat, Andrew Svesko
We examine four dimensional, near-extremal black hole solutions in the presence of a finite boundary obeying conformal boundary conditions, where the conformal class of the induced…
Gravitational Observatories in AdS
Dionysios Anninos, Raúl Arias, Damián A. Galante +1
We consider four-dimensional general relativity with a negative cosmological constant in the presence of a finite size boundary, , for both Euclidean and Lorentzian signature. A…
Cosmological Observatories
Dionysios Anninos, Damián A. Galante, Chawakorn Maneerat
We study the static patch of de Sitter space in the presence of a timelike boundary. We impose that the conformal class of the induced metric and the trace of the extrinsic curvatu…
Gravitational Observatories
Dionysios Anninos, Damián A. Galante, Chawakorn Maneerat
We consider four-dimensional general relativity with vanishing cosmological constant defined on a manifold with a boundary. In Lorentzian signature, the timelike boundary is of the…
