Constraining the High-Density Equation of State with Present and Future NICER Observations Using Physics-Informed Regularized Machine Learning

Utkarsh Atul Deshmukh, Asim Kumar Saha, Ritam Mallick

The paper introduces a physics‑informed conditional invertible neural network that directly maps NICER neutron‑star mass‑radius measurements to central energy density and pressure,…
