General-purpose equations of state for hadron-quark matter: first application to accretion-induced phase transitions in neutron stars
János Takátsy, Henrique Gieg, Tim Dietrich
Strong first-order phase transitions in the cores of neutron stars (NSs) can have profound implications for astrophysical observables, however, their existence remains an open ques…
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 Radio Bursts from Monster Shocks and Flares of Inspiraling Binary Neutron Stars: A Kinetic Model for Double Pulsar
Jan Benáček, Benoît Cerutti, Martin Pohl +2
The coalescence of binary neutron star systems offers unprecedented possibilities for multimessenger observations, including the detection of gravitational waves, gamma-ray bursts,…
Extending the Love-Q Relation to Rapidly Rotating Neutron Stars for Gravitational-Waveform Modelling
Natalie Williams, Tim Dietrich
Gravitational-wave observations of binary neutron star mergers probe the neutron star equation of state through finite-size effects on the waveform. These include the tidal deforma…
Investigating the influence of the full-kinematics treatment for charged-current processes in binary neutron star mergers
Ramon Jaeger, Henrique Gieg, Tim Dietrich
Weak interactions are fundamental in the merger of binary neutron stars (BNS). They provide cooling, change the composition of matter outflows, and can lead to significant secular…
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 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…
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…
Black hole spectroscopy of collapsing and merging neutron stars
Oliver Steppohn, Sebastian H. Völkel, Tim Dietrich
Black hole spectroscopy is an important pillar when studying gravitational waves from black holes and enables tests of general relativity. Most of the gravitational-wave signals ob…
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.…
Magneto-Hydrodynamic Simulations of Eccentric Binary Neutron Star Mergers
Anna Neuweiler, Tim Dietrich, Bernd Brügmann
Highly eccentric binary neutron star mergers exhibit unique dynamical and observational signatures compared to quasi-circular ones in terms of their gravitational wave signal and t…

The detection of GW170817, together with its electromagnetic counterparts, has proven that binary neutron star mergers are of central importance to the field of nuclear astrophysic…
What no one has seen before: gravitational waveforms from warp drive collapse
Katy Clough, Tim Dietrich, Sebastian Khan
Despite originating in science fiction, warp drives have a concrete description in general relativity, with Alcubierre first proposing a spacetime metric that supported faster-than…
