Lessons for adaptive mesh refinement in numerical relativity
Miren Radia, Ulrich Sperhake, Amelia Drew +7
We demonstrate the flexibility and utility of the Berger-Rigoutsos Adaptive Mesh Refinement (AMR) algorithm used in the open-source numerical relativity code GRChombo for generatin…
Weak lensing "post-Born" effects are equivalent to pure lens-lens couplings
Oliver Denton-Turner, Eugene A. Lim
We show that the so-called "post-Born" effects of weak lensing at 4th order are equivalent to lens-lens couplings in the Born Approximation. We demonstrate this by explicitly showi…
Primordial black hole formation with full numerical relativity
Eloy de Jong, Josu C. Aurrekoetxea, Eugene A. Lim
We study the formation of black holes from subhorizon and superhorizon perturbations in a matter dominated universe with 3+1D numerical relativity simulations. We find that there a…
Malaise and remedy of binary boson-star initial data
Thomas Helfer, Ulrich Sperhake, Robin Croft +3
Through numerical simulations of boson-star head-on collisions, we explore the quality of binary initial data obtained from the superposition of single-star spacetimes. Our results…
