Fig. 6: Updated constraints from NICER reanalysis II.
From: Inferring three-nucleon couplings from multi-messenger neutron-star observations
a Shows the posterior distribution function of the LEC c1. c Shows the posterior distribution function of the LEC c3. b Depicts the correlation between c1 and c3 and displays iso-probability contours at the 68% and 90% confidence levels. These distributions are obtained by applying constraints from GW170817 and results from the recent reanalysis of NICER X-ray observations of PSR J003080. Here, we use the mode with mass and radius of ~[1.7M⊙, 14.5 km], i.e., using the hot-spot model PDT-U. Source data for this figure are provided as a Source Data file.
