The Lagrangian Numerical Relativity code SPHINCS_BSSN_v1.0
Stephan Rosswog, Francesco Torsello, Peter Diener
We present version 1.0 of our Lagrangian Numerical Relativity code SPHINCS_BSSN. This code evolves the full set of Einstein equations, but contrary to other Numerical Relativity co…
On the stability of bimetric structure formation
Marcus Högås, Francesco Torsello, Edvard Mörtsell
Bimetric gravity can reproduce the accelerated expansion of the Universe, without a cosmological constant. However, the stability of these solutions to linear perturbations has bee…
Generalized Vaidya solutions in bimetric gravity
Marcus Högås, Mikica Kocic, Francesco Torsello +1
In general relativity, the endpoint of spherically symmetric gravitational collapse is a Schwarzschild--[(A)dS] black hole. In bimetric gravity, it has been speculated that a stati…
Spherical dust collapse in bimetric relativity: Bimetric polytropes
Mikica Kocic, Francesco Torsello, Marcus Högås +1
We present a method for solving the constraint equations in the Hassan-Rosen bimetric theory to determine the initial data for the gravitational collapse of spherically symmetric d…
The mean gauges in bimetric relativity
Francesco Torsello
The choice of gauge in numerical relativity is crucial in avoiding coordinate and curvature singularities. In addition, the gauge can affect the well-posedness of the system. In th…
Covariant BSSN formulation in bimetric relativity
Francesco Torsello, Mikica Kocic, Marcus Högås +1
Numerical integration of the field equations in bimetric relativity is necessary to obtain solutions describing realistic systems. Thus, it is crucial to recast the equations as a…
