The Initial Value Formulation of Dynamical Chern-Simons Gravity
Térence Delsate, David Hilditch, Helvi Witek
We derive an initial value formulation for dynamical Chern-Simons gravity, a modification of general relativity involving parity-violating higher derivative terms. We investigate t…
Higher dimensional Numerical Relativity: code comparison
Helvi Witek, Hirotada Okawa, Vitor Cardoso +5
The nonlinear behavior of higher dimensional black hole spacetimes is of interest in several contexts, ranging from an understanding of cosmic censorship to black hole production i…
Black holes and fundamental fields in Numerical Relativity: initial data construction and evolution of bound states
Hirotada Okawa, Helvi Witek, Vitor Cardoso
Fundamental fields are a natural outcome in cosmology and particle physics and might therefore serve as a proxy for more complex interactions. The equivalence principle implies tha…
