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…
Worldtube excision method for intermediate-mass-ratio inspirals: scalar-field model in 3+1 dimensions
Nikolas A. Wittek, Mekhi Dhesi, Leor Barack +10
Binary black hole simulations become increasingly more computationally expensive with smaller mass ratios, partly because of the longer evolution time, and partly because the lengt…
Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes
Lorenzo Pompili, Alessandra Buonanno, Héctor Estellés +21
We present SEOBNRv5HM, a more accurate and faster inspiral-merger-ringdown gravitational waveform model for quasi-circular, spinning, nonprecessing binary black holes within the ef…
Quasi-equilibrium configurations of binary systems of dark matter admixed neutron stars
Hannes R. Rüter, Violetta Sagun, Wolfgang Tichy +1
Using an adapted version of the SGRID code, we construct for the first time consistent quasi-equilibrium configurations for a binary system consisting of two neutron stars in which…
Eccentric binary black holes: Comparing numerical relativity and small mass-ratio perturbation theory
Antoni Ramos-Buades, Maarten van de Meent, Harald P. Pfeiffer +4
The modelling of unequal mass binary black hole systems is of high importance to detect and estimate parameters from these systems. Numerical relativity (NR) is well suited to stud…
Worldtube excision method for intermediate-mass-ratio inspirals: scalar-field toy model
Mekhi Dhesi, Hannes R. Rüter, Adam Pound +2
The computational cost of inspiral and merger simulations for black-hole binaries increases in inverse proportion to the square of the mass ratio . One factor of…
Hyperbolic Relaxation Method for Elliptic Equations
Hannes R. Rüter, David Hilditch, Marcus Bugner +1
We show how the basic idea of parabolic Jacobi relaxation can be modified to obtain a new class of hyperbolic relaxation schemes that are suitable for the solution of elliptic equa…
The evolution of hyperboloidal data with the dual foliation formalism: Mathematical analysis and wave equation tests
David Hilditch, Enno Harms, Marcus Bugner +2
A long-standing problem in numerical relativity is the satisfactory treatment of future null-infinity. We propose an approach for the evolution of hyperboloidal initial data in whi…
