An Implementation of DF-GHG with Application to Spherical Black Hole Excision
Maitraya K Bhattacharyya, David Hilditch, K Rajesh Nayak +3
We present an implementation of the dual foliation generalized harmonic gauge (DF-GHG) formulation within the pseudospectral code bamps. The formalism promises to give greater free…
Relevance of tidal effects and post-merger dynamics for binary neutron star parameter estimation
Reetika Dudi, Francesco Pannarale, Tim Dietrich +4
Measurements of the properties of binary neutron star systems from gravitational-wave observations require accurate theoretical models for such signals. However, current models are…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Numerical relativity simulations of neutron star merger remnants using conservative mesh refinement
Tim Dietrich, Sebastiano Bernuzzi, Maximiliano Ujevic +1
We study equal and unequal-mass neutron star mergers by means of new numerical relativity simulations in which the general relativistic hydrodynamics solver employs an algorithm th…
Accuracy of numerical relativity waveforms from binary neutron star mergers and their comparison with post-Newtonian waveforms
Sebastiano Bernuzzi, Marcus Thierfelder, Bernd Bruegmann
We present numerical relativity simulations of nine-orbit equal-mass binary neutron star covering the quasicircular late inspiral and merger. The extracted gravitational waveforms…
The trumpet solution from spherical gravitational collapse with puncture gauges
Marcus Thierfelder, Sebastiano Bernuzzi, David Hilditch +2
We investigate the stationary end-state obtained by evolving a collapsing spherical star with the gauges routinely adopted to study puncture black holes. We compare the end-state o…
