Helium as an Indicator of the Neutron-Star Merger Remnant Lifetime and its Potential for Equation of State Constraints
Albert Sneppen, Oliver Just, Andreas Bauswein +9
The time until black hole formation in a binary neutron-star (NS) merger contains invaluable information about the nuclear equation of state (EoS) but has thus far been difficult t…
Gravitational-wave model for neutron star merger remnants with supervised learning
Theodoros Soultanis, Kiril Maltsev, Andreas Bauswein +3
We present a time-domain model for the gravitational waves emitted by equal-mass binary neutron star merger remnants for a fixed equation of state. We construct a large set of nume…
Towards inferring the geometry of kilonovae
Christine E. Collins, Luke J. Shingles, Andreas Bauswein +11
Recent analysis of the kilonova, AT2017gfo, has indicated that this event was highly spherical. This may challenge hydrodynamics simulations of binary neutron star mergers, which u…
Needle in a Bayes Stack: a Hierarchical Bayesian Method for Constraining the Neutron Star Equation of State with an Ensemble of Binary Neutron Star Post-merger Remnants
Alexander W. Criswell, Jesse Miller, Noah Woldemariam +6
Binary neutron star (BNS) post-merger gravitational-wave emission can occur in the aftermath of a BNS merger -- provided the system avoids prompt collapse to a black hole -- as a q…
General relativistic moving-mesh hydrodynamics simulations with AREPO and applications to neutron star mergers
Georgios Lioutas, Andreas Bauswein, Theodoros Soultanis +3
We implement general relativistic hydrodynamics in the moving-mesh code AREPO. We also couple a solver for the Einstein field equations employing the conformal flatness approximati…
Analytic models of the spectral properties of gravitational waves from neutron star merger remnants
Theodoros Soultanis, Andreas Bauswein, Nikolaos Stergioulas
We present a new analytic model describing gravitational wave emission in the post-merger phase of binary neutron star mergers. The model is described by a number of physical param…
Systematics of prompt black-hole formation in neutron star mergers
Andreas Bauswein, Sebastian Blacker, Georgios Lioutas +3
This study addresses the collapse behavior of neutron star (NS) mergers expressed through the binary threshold mass M_thr for prompt black hole (BH) formation, which we determine b…
Constraining the onset density of the hadron-quark phase transition with gravitational-wave observations
Sebastian Blacker, Niels-Uwe F. Bastian, Andreas Bauswein +5
We study the possible occurrence of the hadron-quark phase transition (PT) during the merging of neutron star binaries by hydrodynamical simulations employing a set of temperature…
