Self-interacting scalar dark matter around binary black holes
Josu C. Aurrekoetxea, James Marsden, Katy Clough +1
Gravitational waves can provide crucial insights about the environments in which black holes live. In this work, we use numerical relativity simulations to study the behaviour of s…
New Horizons for Psi: Studying fundamental fields with numerical relativity
Katy Clough
This set of notes was designed to accompany two hours of lectures and practical exercises at the New Horizons for Psi workshop in Lisbon in July 2024 entitled "Studying fundamental…
What no one has seen before: gravitational waveforms from warp drive collapse
Katy Clough, Tim Dietrich, Sebastian Khan
Despite originating in science fiction, warp drives have a concrete description in general relativity, with Alcubierre first proposing a spacetime metric that supported faster-than…
Symmetry restoration and vacuum decay from accretion around black holes
James Marsden, Josu C. Aurrekoetxea, Katy Clough +1
Vacuum decay and symmetry breaking play an important role in the fundamental structure of the matter and the evolution of the universe. In this work we study how the purely classic…
GRDzhadzha: A code for evolving relativistic matter on analytic metric backgrounds
Josu C. Aurrekoetxea, Jamie Bamber, Sam E. Brady +5
GRDzhadzha is an open-source code for relativistic simulations of matter fields on curved spacetimes that admit an analytic description (e.g. stationary black holes). It is based o…
Tunnelling-induced cosmic bounce in the presence of anisotropies
Jean Alexandre, Katy Clough, Silvia Pla
If we imagine rewinding the universe to early times, the scale factor shrinks and the existence of a finite spatial volume may play a role in quantum tunnelling effects in a closed…
