Scalable and sequential inference of the neutron star equation of state with the Einstein Telescope

Thibeau Wouters, Thomas C. K. Ng, Hauke Koehn +4

Future gravitational-wave observatories such as the Einstein Telescope will detect tens of thousands of binary neutron star mergers per year, making gravitational waves a dominant…

A story about a tipsy kangaroo: Reversible jump MCMC for model selection in the analysis of gravitational-wave signals from the coalescence of compact objects

Anna Puecher, Tim Dietrich, Hauke Koehn +4

Bayesian inference is commonly employed in the analysis of gravitational-wave signals not only to estimate the source parameters, but also for model selection. The latter provides…

GRB 241030A: a bright afterglow challenging forward shock emission

J. -G. Ducoin, C. Pellouin, V. Aivazyan +97

Gamma-Ray Burst GRB 241030A (z = 1.411) exhibited a bright afterglow (similar to GRB 221009A), detected across gamma-ray, X-ray, UV, and optical bands, providing a probe of GRB aft…

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions

D. Akl, S. Antier, H. Koehn +105

Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband…

Unified study of nuclear physics and dark matter constraints through gravitational-wave observations of binary neutron star mergers

Nina Kunert, Guilherme Grams, William Newton +5

Understanding the properties of strongly interacting matter at extreme densities is a central problem in fundamental physics, with neutron star mergers offering a natural laborator…

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…

Efficient Bayesian analysis of kilonovae and gamma ray burst afterglows with fiesta

Hauke Koehn, Thibeau Wouters, Peter T. H. Pang +4

Gamma-ray burst (GRB) afterglows and kilonovae (KNe) are electromagnetic transients that can accompany binary neutron star (BNS) mergers. Therefore, studying their emission process…

Leveraging differentiable programming in the inverse problem of neutron stars

Thibeau Wouters, Peter T. H. Pang, Hauke Koehn +5

Neutron stars (NSs) probe the high-density regime of the nuclear equation of state (EOS). However, inferring the EOS from observations of NSs is a computationally challenging task.…

The impact of dark matter on tidal signatures in neutron star mergers with Einstein Telescope

Hauke Koehn, Edoardo Giangrandi, Nina Kunert +3

If dark matter (DM) accumulates inside neutron stars (NS), it changes their internal structure and causes a shift of the tidal deformability from the value predicted by the dense-m…

Probe and Prejudice: Classification of compact objects and model comparison using EOS knowledge

Hauke Koehn, Thibeau Wouters, Henrik Rose +4

Nuclear theory and experiments, alongside astrophysical observations, constrain the equation of state (EOS) of supranuclear-dense matter. Conversely, knowledge of the EOS allows an…

Dynamics of supermassive black hole triples in the ROMULUS25 cosmological simulation

Hauke Koehn, Andreas Just, Peter Berczik +1

For a pair of supermassive black holes (SMBHs) in the remnant of a dual galaxy merger, well-known models exist to describe their dynamical evolution until the final coalescence acc…
