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…

Binary neutron stars in the next-generation era: Multi-messenger detection prospects and constraints on the equation of state, mass distribution, and cosmology

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…

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…

AT2025ulz and S250818k: Investigating early time observations of a subsolar mass gravitational-wave binary neutron star merger candidate

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.…

Detecting electromagnetic counterparts to LIGO/Virgo/KAGRA gravitational wave events with DECam: Neutron Star Mergers

Keerthi Kunnumkai, Antonella Palmese, Amanda M Farah +7

With GW170817 being the only multimessenger gravitational wave (GW) event with an associated kilonova detected so far, there exists a pressing need for realistic estimation of the…

Data-driven approach for modeling the temporal and spectral evolution of kilonova systematic uncertainties

Sahil Jhawar, Thibeau Wouters, Peter T. H. Pang +3

Kilonovae, possible electromagnetic counterparts to neutron star mergers, provide important information about high-energy transient phenomena and, in principle, also allow us to ob…

Kilonova emission from GW230529 and mass gap neutron star-black hole mergers

Keerthi Kunnumkai, Antonella Palmese, Mattia Bulla +3

The detection of the gravitational wave event GW230529, presumably a neutron star-black hole (NSBH) merger, by the LIGO-Virgo-KAGRA (LVK) Collaboration marks an exciting discovery…

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…

An Online Framework for Fitting Fast Transient Lightcurves

Tyler Barna, Brandon Reed, Igor Andreoni +7

The identification of extragalactic fast optical transients (eFOTs) as potential multi-messenger sources is one of the main challenges in time-domain astronomy. However, recent dev…
