Bayesian exploration of weakly interacting models of dark matter admixed neutron stars based on multi-density constraints
Payaswinee Arvikar, Prashant Thakur, Sarmistha Banik
We present a unified Bayesian analysis of Higgs-portal, neutron-decay, and axion-like-particle (ALP)-mediated dark matter in neutron stars within the single-fluid approximation. Us…
Fast Bayesian Updating of the Neutron-Star Equation of State with Neural Posterior and Evidence Estimation
Prashant Thakur
We present two complementary neural routes for microscopic neutron-star EOS inference: truncated sequential neural posterior estimation with mixture importance sampling (TSNPE+MIS)…
Dark matter in neutron stars: two-fluid -mode oscillations in full general relativity
Prashant Thakur, Ishfaq Ahmad Rather, Y. Lim
A dark-matter core and a soft nuclear equation of state can produce similar mass--radius signatures, motivating a complementary probe through the -mode spectrum. We compute quad…
Constraining hyperonic relativistic mean-field models with rapidly rotating neutron stars
Gihwan Nam, Prashant Thakur, Yeunhwan Lim +1
Motivated by the recent mass measurement of the black-widow pulsar PSR~J09520607 with , we investigate how the masses of heavy, rapidly rotating millisec…
Reaction-constrained composition \(g\)-modes in neutron stars with antikaon condensates, hyperons, and \(Δ(1232)\) resonances
Prashant Thakur, Ishfaq Ahmad Rather
We study core composition \(g_1\) modes of cold, nonrotating neutron stars containing antikaon condensates, hyperons, and \(Δ(1232)\) baryons and present, to our knowledge, the fir…
Amortized Simulation-Based Inference of Relativistic Mean-Field Couplings for Neutron-Star Equations of State
Prashant Thakur, Tuhin Malik
We present a simulation-based inference framework for constraining microscopic relativistic mean-field parameters of neutron-star equations of state. Neural posterior estimation is…
Rotational enhancement and stability of protoquark stars during thermal evolution
Adamu Issifu, Andreas Konstantinou, Prashant Thakur +1
We present the first systematic study of rigidly rotating protoquark stars based on isentropic equations of state (EOS) within the density-dependent quark mass (DDQM) framework. Us…
