Constraints on Yukawa-type New Forces from the Lamb Shift in Muonic Hydrogen and Deuterium
Chung-Chien Huang, Li-Bang Wang
We develop an analytical framework to constrain Yukawa-type fifth-force interactions using the Lamb shift in hydrogen and deuterium. The sixfold coordinate-space integral for the e…
Combining the Mass--Radius Posteriors of J0030+0451 Allowing for Unknown Model Systematics
Ryan O'Connor, Chun Huang, Alexander Y. Chen
The NASA Neutron star Interior Composition Explorer (\emph{NICER}) mission measures the X-ray pulse profiles of select millisecond pulsars and uses sophisticated pulse profile mode…
Covariant Energy Density Functionals for Neutron Star Matter Equation of State Modeling: Cross-Comparison Analysis Using \texttt{CompactObject}
João Cartaxo, Chun Huang, Tuhin Malik +5
This study analyzes and contrasts different phenomenological methods used to model the nuclear equation of state (EOS) for neutron star matter based on covariant energy density fun…
Constraining a relativistic mean field model using neutron star mass-radius measurements II: Hyperonic models
Chun Huang, Laura Tolos, Constança Providência +1
We investigate whether measurements of the neutron star mass and radius or the tidal deformability can provide information about the presence of hyperons inside a neutron star. Thi…
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…
