Relativistic Oblique Shocks at Finite Temperature: Detachment Angle, Shock Polars, and the Turning Parameter
Rushikesh Ashok Sonkusale, Anshuman Verma, Ritam Mallick
Oblique shocks are ubiquitous in high-energy astrophysical environments, yet a systematic analytical treatment of how finite upstream temperature influences the maximum deflection…
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 precise mass and radius measurements of neutron stars by NICER have significantly advanced our ability to constrain the properties of matter at supranuclear densities. In this…
Neutron stars with an agnostic Dark sector: Core and Halo configurations from a two-fluid approach
Asit karan, Asim Kumar Saha, Tuhin Malik +2
The study of dark matter admixed neutron stars has the potential to advance our understanding of dark matter particle candidates. However, the large parameter space of dark matter…
A geometric physics-informed machine learning inference for the neutron star maximum mass and the inverse problem
Rounak Mukherjee, Ritam Mallick
The existence of a distinct mass boundary between the heaviest neutron stars and the lightest black holes remains in question. It is an artefact of our ignorance of the properties…
Constraining Twin-Star Existence in Four-Parameter Maxwell Equation of State
Shamim Haque, Atharva Shinde, Asim Kumar Saha +2
Twin stars (TSs) are predicted to exist in nature if the hadron-to-quark phase transition is strong enough to form a new branch of hybrid stars, separated from the branch of neutro…
Dynamical response of twin stars to perturbations
Shamim Haque, Luciano Rezzolla, Ritam Mallick
If a strong first-order phase transition takes place at sufficiently high rest-mass densities in the equation of state (EOS) modelling compact stars, a new branch will appear in th…
Curvature Effect on the Speed of Sound
Anshuman Verma, Asim Kumar Saha, Ritam Mallick
The speed of sound refers to the rate at which information travels from one point to another. It is a positive quantity and bounded by causality. It is defined as the rate of chang…
