An efficient approach to resistive GRMHD simulations of binary neutron star mergers
Miquel Miravet-Tenés, Ian Hawke, Rahime Matur +1
Astrophysical plasmas are often highly conducting, but finite resistivity can nevertheless influence the evolution of strongly magnetised systems. Capturing these effects in genera…
Action based approach to dissipative relativistic fluid systems
G. L. Comer, N. Andersson, T. Celora +1
We develop an action principle for a relativistic two-fluid system with dissipation. The specific constituents of the model - which serves as a proof of principle - are particles a…
Impact of black hole spin on low-mass black hole-neutron star mergers
Rahime Matur, Ian Hawke, Nils Andersson
The recent detection of GW230529 suggests that black hole-neutron star mergers may involve low-mass black holes, potentially producing detectable electromagnetic counterparts. Moti…
Signatures of Low Mass Black Hole-Neutron Star Mergers
Rahime Matur, Ian Hawke, Nils Andersson
The recent observation of the GW230529 event indicates that black hole-neutron star binaries can contain low-mass black holes. Since lower mass systems are more favourable for tida…
Higher-level large-eddy filtering strategy for general relativistic fluid simulations
Thomas Celora, Nils Andersson, Ian Hawke +2
Nonlinear simulations of neutron star mergers are complicated by the need to represent turbulent dynamics. As we cannot (yet) perform simulations that resolve accurately both the g…
