This paper investigates the properties of matter at the extremely high densities found in neutron star cores, using observational data from NICER and gravitational wave (GW) detections. The study focuses on data from PSR J0614-3329 and employs Bayesian inference to constrain the equation of state (EoS) of this matter. The findings suggest that observational constraints favor a smoother EoS, potentially delaying phase transitions and impacting the maximum mass of neutron stars. The paper highlights the importance of observational data in refining our understanding of matter under extreme conditions.
