Bayesian EOS inference with χEFT uncertainty priors and LIGO/NICER data yields posteriors consistent with prior work, a stiffening above 3n0, negligible pQCD impact, and an inferred symmetry-energy slope L of 42.6-56.7 MeV.
Hybrid star models with constant sound speed quark matter match NICER data for PSR J0740+6620 and PSR J0030+0451 only when the energy density discontinuity at the phase transition is small and the quark sound speed is relatively high.

Can a hybrid star with constant sound speed parametrization explain the new NICER mass-radius measurements ?
Hybrid star models with constant sound speed quark matter match NICER data for PSR J0740+6620 and PSR J0030+0451 only when the energy density discontinuity at the phase transition is small and the quark sound speed is relatively high.
