Fig. 3: Correlation between the long-ringdown slope and the TOV properties.
From: Constraining the equation of state in neutron-star cores via the long-ringdown signal
Data and fits illustrating the correlations between the slope of the radiated quantities \({\widehat{E}}_{{{{\rm{GW}}}}}\) and \({\widehat{J}}_{{{{\rm{GW}}}}}\) normalized to the merger values, and pTOV (top row) or nTOV (bottom row), and for different mass ratios (different columns). The dark (light) shaded regions denote 68%(95%) credible intervals for the bilinear model (1), while the solid lines denote the mean value. A marginalization over the remaining EOS quantity in the bilinear model was performed. Also shown are data points for two microscopic EOS models, one of which (HS-DD2) is disfavored by astrophysical data. Source data for this figure are provided as a Source Data file.
