Late-time tails in nonlinear evolutions of merging black holes
Marina De Amicis, Hannes Rüter, Gregorio Carullo +17
We uncover late-time gravitational-wave tails in fully nonlinear 3+1 dimensional numerical relativity simulations of merging black holes, using the highly accurate SpEC code. We ac…
A Review of Gravitational Memory and BMS Frame Fixing in Numerical Relativity
Keefe Mitman, Michael Boyle, Leo C. Stein +8
Gravitational memory effects and the BMS freedoms exhibited at future null infinity have recently been resolved and utilized in numerical relativity simulations. With this, gravita…
Binary neutron star mergers using a discontinuous Galerkin-finite difference hybrid method
Nils Deppe, Francois Foucart, Marceline S. Bonilla +18
We present a discontinuous Galerkin-finite difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohy…
Robustness of neutron star merger simulations to changes in neutrino transport and neutrino-matter interactions
Francois Foucart, Patrick Chi-Kit Cheong, Matthew D. Duez +3
Binary neutron star mergers play an important role in nuclear astrophysics: their gravitational wave and electromagnetic signals carry information about the equation of state of co…
High-Precision Ringdown Surrogate Model for Non-Precessing Binary Black Holes
Lorena Magaña Zertuche, Leo C. Stein, Keefe Mitman +11
Highly precise and robust waveform models are required as improvements in detector sensitivity enable us to test general relativity with more precision than ever before. In this wo…
High angular momentum hot differentially rotating equilibrium star evolutions in conformally flat spacetime
Patrick Chi-Kit Cheong, Nishad Muhammed, Pavan Chawhan +5
The conformal flatness approximation to the Einstein equations has been successfully used in many astrophysical applications such as initial data constructions and dynamical simula…
