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…
Covariant approach to relativistic large-eddy simulations: Lagrangian filtering
T. Celora, M. J. Hatton, I. Hawke +1
We present a proof-of-principle implementation of the first fully covariant filtering scheme applied to relativistic fluid turbulence. The filtering is performed with respect to sp…
The impact of nuclear reactions on the neutron-star g-mode spectrum
A. R. Counsell, F. Gittins, N. Andersson
Mature neutron stars are expected exhibit gravity g-modes due to stratification caused by varying composition. These modes are affected by nuclear reactions, leading to complex (da…
