Fast and Accurate Prediction of Neutron Star Structure with Deep Neural Networks
Kaushikk V N, Bhaskar Biswas, Stephan Rosswog
Solving the Tolman--Oppenheimer--Volkoff (TOV) equations, together with the tidal perturbation equations, for large numbers of equation-of-state (EOS) samples is a major computatio…
Binary neutron star mergers with SPHINCS_BSSN: temperature-dependent equations of state and damping of constraint violations
Bhaskar Biswas, Stephan Rosswog, Peter Diener +1
Neutron star mergers hold the key to several grand challenges of contemporary (astro-)physics. In view of the upcoming next generation of ground-based detectors, it is crucial to k…
Equation of State Extrapolation Systematics: Parametric vs. Nonparametric Inference of Neutron Star Structure
Bhaskar Biswas
The equation of state (EOS) of cold dense matter is a central open problem in nuclear astrophysics. Its inference is hindered by the lack of \textit{ab initio} control above about…
Systematics from NICER Pulse Profiles Drive Uncertainty in Multi-Messenger Inference of the Neutron Star Equation of State
Bhaskar Biswas, Prasanta Char
We present new constraints on the neutron star equation of state (EOS) and mass distribution using a unified Bayesian inference framework that incorporates latest NICER measurement…
PSR J0952-0607: Probing the Stiffest Equations of State and r-Mode Suppression Mechanisms
Zeyue Wu, Bhaskar Biswas, Stephan Rosswog
We analyze PSR J0952-0607, the most massive and fastest spinning neutron star observed to date, to refine constraints on the neutron star equation of state (EoS) and investigate it…
Compact object of HESS J1731-347 and its implication on neutron star matter
Prasanta Char, Bhaskar Biswas
In this work, we investigate the impact of the possibility of a small, subsolar mass compact star, such as the recently reported central compact object of HESS J1731-347, on the eq…
Simultaneously Constraining the Neutron Star Equation of State and Mass Distribution through Multimessenger Observations and Nuclear Benchmarks
Bhaskar Biswas, Stephan Rosswog
With ongoing advancements in nuclear theory and experimentation, together with a growing body of neutron star (NS) observations, a wealth of information on the equation of state (E…
Joint Inference of Population, Cosmology, and Neutron Star Equation of State from Gravitational Waves of Dark Binary Neutron Stars
Tathagata Ghosh, Bhaskar Biswas, Sukanta Bose +1
Gravitational waves (GWs) from binary neutron stars (BNSs) are expected to be accompanied by electromagnetic (EM) emissions, which help identify the host galaxy. Since GWs directly…
