Comparing twist-free axisymmetric gravitational waves near the black hole threshold
Ananya Adhikari, Tomáš Ledvinka, Daniela Cors +4
The threshold of black hole formation in axisymmetric vacuum gravity is proving to be more complicated than had been anticipated but, following recent advances, a consensus between…
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…
Hair is complicated: Gravitational waves from stable and unstable boson-star mergers
Bo-Xuan Ge, Eugene A. Lim, Ulrich Sperhake +5
We explore the gravitational-wave emission from head-on collisions of equal-mass solitonic boson-star binaries from simulations spanning a two-dimensional parameter space, consisti…
Twist-free axisymmetric critical collapse of a complex scalar field
Krinio Marouda, Daniela Cors, Hannes R. Rüter +2
Critical phenomena in gravitational collapse are characterized by the emergence of surprising structure in solution space, namely the appearance of universal power-laws and periodi…
Boson star head-on collisions with constraint-violating and constraint-satisfying initial data
Florian Atteneder, Hannes R. Rüter, Daniela Cors +3
Simulations of binary collisions involving compact objects require initial data that satisfy the constraint equations of general relativity. For binary boson star simulations it is…
Critical phenomena in the collapse of gravitational waves
Thomas W. Baumgarte, Bernd Brügmann, Daniela Cors +6
Fine-tuning generic but smooth spherically-symmetric initial data for general relativity to the threshold of dynamical black hole formation creates arbitrarily large curvatures, me…
Adaptive hp-Refinement for Spectral Elements in Numerical Relativity
Sarah Renkhoff, Daniela Cors, David Hilditch +1
When a numerical simulation has to handle a physics problem with a wide range of time-dependent length scales, dynamically adaptive discretizations can be the method of choice. We…
