Bayesian Inference of Neutron Star Properties in Gravity Using NICER Observations
Sneha Pradhan, N. K. Patra, Kai Zhou +1
In this work, we investigate neutron stars (NSs) in the strong field regime within the framework of symmetric teleparallel gravity, considering three representative models:…
Learning the relations between neutron star and nuclear matter properties with symbolic regression
N. K. Patra, Tuhin Malik, Kai Zhou +1
The equation of state (EOS) of dense matter in neutron stars (NSs) remains uncertain, particularly at supra-nuclear densities where complex nuclear interactions and the potential p…
Bayesian Analysis of the Neutron Star Equation of State and Model Comparison: Insights from PSR J0437+4715, PSR J0614+3329, and Other Multi-Physics Data
Sk Md Adil Imam, N. K. Patra
We perform a comprehensive Bayesian analysis to constrain the neutron star (NS) equation of state (EoS) using a wide range of terrestrial and astrophysical data. The terrestrial in…
Inferring the Equation of State from Neutron Star Observables via Machine Learning
N. K. Patra, Tuhin Malik, Helena Pais +3
We have conducted an extensive study using a diverse set of equations of state (EoSs) to uncover strong relationships between neutron star (NS) observables and the underlying EoS p…
Calibrating global behaviour of equation of state by combining nuclear and astrophysics inputs in a machine learning approach
Sk Md Adil Imam, Prafulla Saxena, Tuhin Malik +2
We implemented symbolic regression techniques to identify suitable analytical functions that map various properties of neutron stars (NSs), obtained by solving the Tolman-Oppenheim…
Bayesian and Principal Component Analyses of Neutron Star Properties
N. K. Patra
A Bayesian method is used in this extensive work to generate a large set of minimally constrained equations of state (EOSs) for matters in neutron stars (NS). These EOSs are analyz…
Establishing connection between neutron star properties and nuclear matter parameters through a comprehensive multivariate analysis
N. K. Patra, Prafulla Saxena, B. K. Agrawal +1
We have attempted to mitigate the challenge of connecting the neutron star (NS) properties with the nuclear matter parameters that describe equations of state (EoSs). The efforts t…
Systematic analysis of the impacts of symmetry energy parameters on neutron star properties
N. K. Patra, Anagh Venneti, Sk Md Adil Imam +2
The impacts of various symmetry energy parameters on the properties of neutron stars (NSs) have been recently investigated, and the outcomes are at variance, as summarized in Table…
High-Density behavior of symmetry energy and speed of sound in the dense matter within an effective chiral model
Prashant Thakur, N. K. Patra, T. K. Jha +1
With an effective chiral model, we investigate how the mesonic cross couplings and affect the density content of the symmetry energy and its higher-order slope paramete…
Effect of the -cut potential on the properties of neutron stars with or without a hyperonic core
N. K. Patra, B. K. Sharma, A. Reghunath +2
Motivated by the recent observation of high-mass pulsars (), we employ the -cut potential on the equation of state (EOS) of high-density matter and the pro…
Nearly model-independent constraints on dense matter equation of state in a Bayesian approach
N. K. Patra, Sk Md Adil Imam, B. K. Agrawal +2
We apply Bayesian approach to construct a large number of minimally constrained equations of state (EOSs) and study their correlations with a few selected properties of a neutron s…
Bayesian reconstruction of nuclear matter parameters from the equation of state of neutron star matter
Sk Md Adil Imam, N. K. Patra, C. Mondal +2
The nuclear matter parameters (NMPs), those underlie in the construction of the equation of state (EoS) of neutron star matter, are not directly accessible. The Bayesian approach i…
