Gravitational Magnus effect from scalar dark matter
Zipeng Wang, Thomas Helfer, Dina Traykova +2
In fluid dynamics, the Magnus effect is the force perpendicular to the motion of a spinning object as it moves through a medium. In general relativity, an analogous effect exists f…
GRDzhadzha: A code for evolving relativistic matter on analytic metric backgrounds
Josu C. Aurrekoetxea, Jamie Bamber, Sam E. Brady +5
GRDzhadzha is an open-source code for relativistic simulations of matter fields on curved spacetimes that admit an analytic description (e.g. stationary black holes). It is based o…
Relativistic drag forces on black holes from scalar dark matter clouds of all sizes
Dina Traykova, Rodrigo Vicente, Katy Clough +4
We use numerical simulations of scalar field dark matter evolving on a moving black hole background to confirm the regime of validity of (semi-)analytic expressions derived from fi…
Properties of scalar wave emission in a scalar-tensor theory with kinetic screening
Masaru Shibata, Dina Traykova
We study numerically the scalar wave emission by a non-spherical oscillation of neutron stars in a scalar-tensor theory of gravity with kinetic screening, considering both the mono…
GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
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…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Accretion of a Symmetry Breaking Scalar Field by a Schwarzschild Black Hole
Dina Traykova, Jonathan Braden, Hiranya V. Peiris
We simulate the behaviour of a Higgs-like field in the vicinity of a Schwarzschild black hole using a highly accurate numerical framework. We consider both the limit of the zero-te…
