Three-nucleon forces are crucial for the accurate description of nuclear systems, including dense matter probed in neutron stars. We explore nuclear Hamiltonians that reproduce two-nucleon scattering data and properties of light nuclei, but differ in the three-nucleon interactions among neutrons. While no significantly improved constraints can be obtained from current astrophysical data, we show that observations of neutron star mergers by next-generation detectors like the proposed Einstein Telescope could provide strong evidence to distinguish between these Hamiltonians.

  1. nmma: An extended Bayesian framework for Nuclear Multimessenger Astronomy in the Era of Next-Generation Detectors

    astro-ph.IM 2026-07 accept novelty 6.0 of 10

    nmma now jointly samples nuclear EoS parameters with GW and EM data via TOV emulators and Fiesta surrogates, delivering 20–60× speedups and future H0–nuclear constraints.

  2. Constraining Hamiltonians from chiral effective field theory with neutron-star data

    nucl-th 2026-01 conditional novelty 6.0 of 10

    Neutron-star data, run through fast emulators, directly constrain the six two-nucleon low-energy constants of an N2LO chiral Hamiltonian, with future detectors able to strongly pin down the 3P1 channel.
