Testing the Paradigm of Nuclear Many-Body Theory
Omar Benhar
Nuclear many-body theory is based on the tenet that nuclear systems can be accurately described as collections of point-like particles. This picture, while providing a remarkably a…

The interpretation of the available and forthcoming data obtained from multimessenger astrophysical observations -- potentially providing unprecedented access to neutron star prope…
Impact of three-nucleon forces on gravitational wave emission from neutron stars
Lucas Tonetto, Andrea Sabatucci, Omar Benhar
The detection of gravitational radiation, emitted in the aftermath of the excitation of neutron star quasi-normal modes, has the potential to provide unprecedented access to the pr…
Unraveling the Flux-Averaged Neutrino-Nucleus Cross Section
Omar Benhar
The interpretation of the nuclear cross sections measured using accelerator neutrino beams involve severe difficulties, arising primarily from the average over the incoming neutrin…

The observation of the gravitational wave signal GW170817, consistent with emission from the inspiral of a binary neutron-star system, provided information on the tidal deformation…
Scale Dependence of Nucleon-Nucleon Potentials
Omar Benhar
The scale-dependence of the nucleon-nucleon interaction, which in recent years has been extensively analysed within the context of chiral effective field theory, is, in fact, inher…
