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-…
Consistent Treatment of Muons in Binary Neutron Star Mergers
Henrique Gieg, Ramon Jaeger, Maximiliano Ujevic +1
We present a set of numerical-relativity binary neutron star merger simulations incorporating muons and muonic reactions for two baseline baryonic equations-of-state. In order to i…
Investigating the impact of quasi-universal relations on neutron star constraints in third-generation detectors
Natalie Williams, Anna Puecher, Guilherme Grams +2
Gravitational-wave observations of binary neutron star systems can shed light on the currently unknown dense matter equation of state. The equation of state determines a large numb…
Numerical simulations of Scalar Dark Matter Around Binary Neutron Star mergers
Rohan Srikanth, Tim Dietrich, Katy Clough
Binary neutron star mergers provide a laboratory for probing fundamental physics through their gravitational-wave emission and electromagnetic counterparts. In particular, they may…
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…
