Fast gravitational waveform models for quasi-circular coalescences of neutron star--black hole binaries
Felip A. Ramis Vidal, Adrian Abac, Marta Colleoni +5
We present IMRPhenomXHM_NSBH and SEOBNRv5HM_ROM_NRTidalv3_NSBH, the first two frequency-domain models for gravitational-wave signals from quasi-circular, aligned-spin neutron star-…
Exploring the Dynamics of General Relativistic Binary-Single and Binary-Binary Encounters of Black Holes
Felix M. Heinze, Bernd Brügmann, Tim Dietrich +1
In this exploratory study, we demonstrate the capability of the numerical-relativity code BAM to simulate fully relativistic black-hole binary-single and binary-binary encounters.…
Numerical simulations of black hole-neutron star mergers with equal and near-equal mass ratios
Ivan Markin, Mattia Bulla, Tim Dietrich
The detection of GW230529_181500 suggested the existence of more symmetric black hole-neutron star mergers where the black hole mass can be as low as 2.6 times that of the neutron…
Challenging a binary neutron star merger interpretation of GW230529
Ivan Markin, Anna Puecher, Mattia Bulla +1
GW230529_181500 represented the first gravitational-wave detection with one of the component objects' mass inferred to lie in the previously hypothesized mass gap between the heavi…
General-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers: The influence of spin on the multi-messenger picture
Anna Neuweiler, Henrique Gieg, Henrik Rose +8
The rich phenomenology of binary neutron star mergers offers a unique opportunity to test general relativity, investigate matter at supranuclear densities, and learn more about the…
General-Relativistic Hydrodynamics Simulation of a Neutron Star - Sub-Solar-Mass Black Hole Merger
Ivan Markin, Anna Neuweiler, Adrian Abac +4
Over the last few years, there has been an increasing interest in sub-solar mass black holes due to their potential to provide valuable information about cosmology or the black hol…
