Numerical simulations of low-mass black hole-neutron star mergers with moderate eccentricities
Ivan Markin, Gonzalo Morrás, Tim Dietrich
A confident detection of orbital eccentricity in gravitational-wave signals from black hole-neutron star systems would be a strong indicator of their dynamical formation origin. Wh…
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-…
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…
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…
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…
The error budget of binary neutron star merger simulations for configurations with high spin
Hao-Jui Kuan, Ivan Markin, Maximiliano Ujevic +4
Numerical-relativity simulations offer a unique approach to investigating the dynamics of binary neutron star mergers and provide the most accurate predictions of waveforms in the…
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.…
Black-hole formation in binary neutron star mergers: The impact of spin on the prompt-collapse scenario
Federico Schianchi, Maximiliano Ujevic, Anna Neuweiler +3
Accurate modeling of the multi-messenger signatures connected to binary neutron star mergers requires proper knowledge on the final remnant's fate and the conditions under which bl…
Chemical Distribution of the Dynamical Ejecta in the Neutron Star Merger GW170817
Shreya Anand, Peter T. H. Pang, Mattia Bulla +11
GW170817 and its associated electromagnetic counterpart AT2017gfo continue to be a treasure trove as observations and modeling continue. Recent precision astrometry of AT2017gfo wi…
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…
Impact of jets on kilonova photometric and polarimetric emission from binary neutron star mergers
Manisha Shrestha, Mattia Bulla, Lorenzo Nativi +3
A merger of binary neutron stars creates heavy unstable elements whose radioactive decay produces a thermal emission known as a kilonova. In this paper, we predict the photometric…
