Hauke Koehn, Thibeau Wouters, Gilad Sadeh +5
Next-generation gravitational-wave (GW) observatories will provide crucial insights into the nature of neutron star (NS) matter and the cosmological expansion history. We estimate…
nmma: An extended Bayesian framework for Nuclear Multimessenger Astronomy in the Era of Next-Generation Detectors
Henrik Rose, Hauke Koehn, Thibeau Wouters +4
Context. The joint analysis of different (astro-)physical messengers, in particular gravitational-wave data and electromagnetic follow-up observations, allows us to establish, expl…
Detecting Tidal Resonances in Binary Neutron Stars
Fabian Gittins, Harsh Narola, Thibeau Wouters +3
As a binary neutron star inspirals due to the emission of gravitational waves, the rising tidal frequency resonantly excites vibrational modes. These oscillations are seismological…
Kilonova and progenitor properties of merger-driven gamma-ray bursts
P. Singh, G. Stratta, A. Rossi +6
Gamma-Ray Burst (GRB) prompt and afterglow emission, as well as a kilonova (KN), are the expected electromagnetic (EM) counterparts of Binary Neutron Star (BNS) and Neutron Star --…
Incorporating neutron star physics into gravitational wave inference with physics-informed priors using normalizing flows
Thibeau Wouters, Peter T. H. Pang, Tim Dietrich +1
Bayesian inference, widely used in gravitational-wave parameter estimation, depends on the choice of priors, i.e., on our previously existing knowledge. However, to investigate neu…

Xander J. Hall, Malte Busmann, Hauke Koehn +32
Over the past LIGO--Virgo--KAGRA (LVK) observing runs, it has become increasingly clear that identifying the next electromagnetic counterparts to gravitational-wave (GW) neutron st…
Analyzing GW231109_235456 and understanding its potential implications for population studies, nuclear physics, and multi-messenger astronomy
Thibeau Wouters, Anna Puecher, Peter T. H. Pang +1
We study the gravitational-wave trigger GW231109_235456, a sub-threshold binary neutron star merger candidate observed in the first part of the fourth observing run of the LIGO-Vir…
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…
Revealing tensions in neutron star observations with pressure anisotropy
Peter T. H. Pang, Stephanie M. Brown, Thibeau Wouters +1
Pressure isotropy, i.e., equality between radial and tangential pressure, is often assumed when studying neutron stars. However, mechanisms such as pion/kaon condensation, magnetic…
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.…
