Neural-Accelerated Bayesian Calibration of Chiral Mean-Field Models to Nuclear Saturation and Vacuum Properties
Isaac Legred, Mateus Reinke Pelicer, Veronica Dexheimer +2
The paper presents a neural‑accelerated Bayesian framework that uses a surrogate neural network to efficiently calibrate chiral mean‑field nuclear interaction models against nuclea…
Studying the QCD Matter produced in Heavy-Ion Collisions using the MUSES Calculation Engine
Johannes Jahan, Kevin P. Pala, Yumu Yang +42
The equation of state of hot and dense matter is essential for describing heavy-ion collisions at all collision energies. Here, we explore the capabilities of the latest version of…
Impact of numerical-relativity waveform calibration on parametrized post-Einsteinian tests
Simone Mezzasoma, Carl-Johan Haster, Nicolás Yunes
Testing general relativity in the strong-field and highly dynamical regime is now possible through current gravitational-wave observations, where even a single high-quality detecti…
A New Spin on Dissipative Tides: First-Post-Newtonian Effects in Compact Binary Inspirals
Anand Balivada, Abhishek Hegade K. R., Nicolás Yunes
Tidal dissipation in spinning compact binaries imprints characteristic corrections on the late-inspiral gravitational-wave signal. We develop a next-to-leading order post-Newtonian…
Donutization Inside Neutron Stars: Shell-Localized Scalar Fields
Hao-Jui Kuan, Alan Tsz-Lok Lam, Jacquelyn Noronha-Hostler +1
Heavy scalar fields ( eV) in scalar-tensor gravity are expected to be hidden from neutron-star observations because their Compton wavelength is sub-stellar. We…
Universal Relations with Dynamical Tides
Jayana A. Saes, Abhishek Hegade K. R., Nicolás Yunes
Observations of neutron stars and the precise measurement of their macroscopic properties have provided valuable insights into fundamental physics, both by constraining the behavio…
