Impact of the Scalar Isovector -meson on the description of nuclear matter and neutron star properties
Lavínia Gabriela Teodoro dos Santos, Tuhin Malik, Constança Providência
The implications of including the scalar isovector -meson in a relativistic mean-field description of nuclear matter are discussed. A Bayesian inference approach is used to dete…
CompactObject: An open-source Python package for full-scope neutron star equation of state inference
Chun Huang, Tuhin Malik, João Cartaxo +14
The CompactObject package is an open-source software framework developed to constrain the neutron star equation of state (EOS) through Bayesian statistical inference. It integrates…
Bayesian evaluation of hadron-quark phase transition models through neutron star observables in light of nuclear and astrophysics data
Debanjan Guha Roy, Anagh Venneti, Tuhin Malik +2
We investigate the role of hybrid and nucleonic equations of state (EOSs) within neutron star (NS) interiors using Bayesian inference to evaluate their alignment with recent observ…
Feasibility of dark matter admixed neutron star based on recent observational constraints
Prashant Thakur, Tuhin Malik, Arpan Das +3
The equation of state (EOS) for neutron stars is modeled using the Relativistic Mean Field (RMF) approach with a mesonic nonlinear (NL) interaction, a modified sigma cut potential…
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…
Nambu-Jona-Lasinio description of hadronic matter from a Bayesian approach
K. D. Marquez, Tuhin Malik, Helena Pais +2
A microscopic nuclear matter formalism with explicit chiral symmetry based on the Nambu Jona-Lasinio model is considered to describe nuclear matter. To reproduce nuclear matter pro…
Constraining the high-density behavior of nuclear symmetry energy with direct Urca processes
Olfa Boukari, Tuhin Malik, Aziz Rabhi +1
The density dependence of the symmetry energy in relativistic mean-field models with density dependent couplings is discussed in terms of the possible opening of nucleonic direct U…
Calibrating the medium effects of light clusters in heavy-ion collisions
Tiago Custódio, Alex Rebillard-Soulié, Rémi Bougault +5
We propose a Bayesian inference estimation of in-medium modification of the cluster self-energies from light nuclei multiplicities measured in selected samples of central $^{136,12…
Hybrid Star Properties with NJL and MFTQCD Model: A Bayesian Approach
Milena Albino, Tuhin Malik, Márcio Ferreira +1
The composition of the core of neutron stars (NS) is still under debate. One possibility is that because of the high densities reached in their cores, matter could be deconfined in…
Astrophysics and Nuclear Physics Informed Interactions in Dense Matter: Inclusion of PSR J0437-4715
Tuhin Malik, Veronica Dexheimer, Constança Providência
We investigate how vector-isoscalar and vector-isovector interactions can be determined within the density regime of neutron stars (NSs), while fulfilling nuclear and astrophysics…
The footprint of nuclear saturation properties on the neutron star mode oscillation frequencies: a machine learning approach
Deepak Kumar, Tuhin Malik, Hiranmaya Mishra
We investigate the intricate relationships between the non-radial \(f\) mode oscillation frequencies of neutron stars (NS)s and the corresponding nuclear matter equation of state (…
Unified neutron star equations of state calibrated to nuclear properties
Tuhin Malik, Helena Pais, Constança Providência
Recently, in Malik23, a dataset of several EoS for purely nucleonic stellar matter based on a non-linear RMF model prescription, and constrained to properties of nuclear matter, to…
Towards Uncovering Dark Matter Effects on Neutron Star Properties: A Machine Learning Approach
Prashant Thakur, Tuhin Malik, T. K. Jha
In recent years, researchers have become increasingly interested in understanding how dark matter affects neutron stars, helping them to better understand complex astrophysical phe…
Implications of comprehensive nuclear and astrophysics data on the equations of state of neutron star matter
