Bayesian inferences on covariant density functionals from multimessenger astrophysical data: Influences of parametrizations of density dependent couplings

Armen Sedrakian, Fu-Hu Liu, Guo-Jun Wei, Jia-Jie Li, Qing-Feng Li, Yong-Jia Wang

Different parametrizations of density dependence in covariant density functionals produce comparable Bayesian inferences from multimessenger data yet leave significant differences in the equation of state and symmetry energy at suprasupersa

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our analysis demonstrates that although all considered parametrizations yield broadly comparable inferences, the differences in the equation of state and the symmetry energy remain significant at suprasaturation densities, reflecting the sensitivity to the chosen functional form of the density dependence.

C2weakest assumption

The assumption that the selected functional forms for density dependence, together with the multimessenger data, are sufficient to capture the essential physics of dense matter without missing interactions or requiring additional degrees of freedom beyond those adjusted in the Bayesian analysis.

C3one line summary

Different parametrizations of density dependence in covariant density functionals produce significant variations in the high-density equation of state and symmetry energy, with rational-function forms providing flexibility when saturation properties are adjusted and constrained by multimessenger ast
