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…

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-…

A 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, but neutron star mergers provide a natural laboratory…

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…

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…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…
