Equation of State Extrapolation Systematics: Parametric vs. Nonparametric Inference of Neutron Star Structure
Bhaskar Biswas
The equation of state (EOS) of cold dense matter is a central open problem in nuclear astrophysics. Its inference is hindered by the lack of \textit{ab initio} control above about…

Systematics from NICER Pulse Profiles Drive Uncertainty in Multi-Messenger Inference of the Neutron Star Equation of State
Bhaskar Biswas, Prasanta Char
We present new constraints on the neutron star equation of state (EOS) and mass distribution using a unified Bayesian inference framework that incorporates latest NICER measurement…

PSR J0952-0607: Probing the Stiffest Equations of State and r-Mode Suppression Mechanisms
Zeyue Wu, Bhaskar Biswas, Stephan Rosswog
We analyze PSR J0952-0607, the most massive and fastest spinning neutron star observed to date, to refine constraints on the neutron star equation of state (EoS) and investigate it…
