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…
Hunting intermediate-mass black holes with LISA binary radial velocity measurements
Vladimir Strokov, Giacomo Fragione, Kaze W. K. Wong +2
Despite their potential role as massive seeds for quasars, in dwarf galaxy feedback, and in tidal disruption events, the observational evidence for intermediate-mass black holes (I…
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…
Dynamical friction from scalar dark matter in the relativistic regime
Dina Traykova, Katy Clough, Thomas Helfer +3
Light bosonic scalars (e.g. axions) may form clouds around black holes via superradiant instabilities, or via accretion if they form some component of the dark matter. It has been…
