Twist and higher modes of a complex scalar field at the threshold of collapse
Krinio Marouda, Daniela Cors, Hannes R. Rüter +2
We investigate the threshold of collapse of a massless complex scalar field in axisymmetric spacetimes under the ansatz of Choptuik et al. 2004, in which a symmetry depending on th…
Charged Scalar Field at Future Null Infinity via Nonlinear Hyperboloidal Evolution
João D. Álvares, Alex Vañó-Viñuales
Quasinormal modes and power-law late-time decay tails of a charged scalar field on a charged black hole have been considered in the literature, and here we use the hyperboloidal fo…
Free Hyperboloidal Evolution of the Einstein-Maxwell-Klein-Gordon System
João D. Álvares, Alex Vaño-Viñuales
We present simulations of the Einstein-Maxwell-Klein-Gordon system on compactified hyperboloidal slices. To the best of our knowledge, this is the first time that this setup is evo…
Conformal diagrams for stationary and dynamical strong-field hyperboloidal slices
Alex Vañó-Viñuales
Conformal Carter-Penrose diagrams are used for the visualization of hyperboloidal slices, which are smooth spacelike slices reaching null infinity. The focus is on the Schwarzschil…
A catalogue of precessing black-hole-binary numerical-relativity simulations
Eleanor Hamilton, Edward Fauchon-Jones, Mark Hannam +9
We present a public catalogue of numerical-relativity binary-black-hole simulations. The catalogue contains datasets from 80 distinct configurations of precessing binary-black-hole…
Decay of solutions of the wave equation in cosmological spacetimes -- a numerical analysis
Flavio Rossetti, Alex Vañó-Viñuales
We numerically evolve spherically symmetric solutions to the linear wave equation on some expanding Friedmann-Lemaître-Robertson-Walker (FLRW) spacetimes and study the respective a…
The final twist: A model of gravitational waves from precessing black-hole binaries through merger and ringdown
Eleanor Hamilton, Lionel London, Jonathan E. Thompson +6
We present PhenomPNR, a frequency-domain phenomenological model of the gravitational-wave (GW) signal from binary-black-hole mergers that is tuned to numerical relativity (NR) simu…
The Hyperboloidal Numerical Evolution of a Good-Bad-Ugly Wave Equation
Edgar Gasperin, Shalabh Gautam, David Hilditch +1
One method for the numerical treatment of future null-infinity is to decouple coordinates from the tensor basis and choose each in a careful manner. This dual-frame approach is ham…
Spherical symmetry as a test case for unconstrained hyperboloidal evolution II: gauge conditions
Alex Vañó-Viñuales, Sascha Husa
We present numerical solutions of the hyperboloidal initial value problem for a self-gravitating scalar field in spherical symmetry, using a variety of standard hyperbolic slicing…
Spherical symmetry as a test case for unconstrained hyperboloidal evolution
Alex Vañó-Viñuales, Sascha Husa, David Hilditch
We consider the hyperboloidal initial value problem in numerical relativity, motivated by the goal to evolve radiating compact objects such as black hole binaries with a numerical…
