Inferring three-nucleon couplings from multi-messenger neutron-star observations
Rahul Somasundaram, Isak Svensson, Soumi De +5
Understanding the interactions between nucleons in dense matter is an important challenge in theoretical physics. Effective field theories have emerged as the dominant approach to…
Unified nonparametric equation-of-state inference from the neutron-star crust to perturbative-QCD densities
Eliot Finch, Isaac Legred, Katerina Chatziioannou +3
Perturbative quantum chromodynamics (pQCD), while valid only at densities exceeding those found in the cores of neutron stars, could provide constraints on the dense-matter equatio…
Inferring the neutron star equation of state with nuclear-physics informed semiparametric models
Sunny Ng, Isaac Legred, Lami Suleiman +3
Over the past decade, an abundance of information from neutron-star observations, nuclear experiments and theory has transformed our efforts to elucidate the properties of dense ma…
The interplay of astrophysics and nuclear physics in determining the properties of neutron stars
Jacob Golomb, Isaac Legred, Katerina Chatziioannou +1
Neutron star properties depend on both nuclear physics and astrophysical processes, and thus observations of neutron stars offer constraints on both large-scale astrophysics and th…
Astrophysical constraints on neutron star -modes with a nonparametric equation of state representation
Sailesh Ranjan Mohanty, Utkarsh Mali, H. C. Das +2
We constrain the fundamental-mode (-mode) oscillation frequencies of nonrotating neutron stars using a phenomenological Gaussian process model for the unknown dense-matter equat…
