Synchrotron polarization of anisotropic electron distribution in GRB prompt emission
Kang-Fa Cheng, Kai-Xian Luo, Xiao-Hong Zhao +7
In gamma-ray bursts (GRBs), the electron pitch angle () is usually assumed to be isotropically distributed. However, recent numerical simulations indicate that only the high-en…

Inverse-mapped density-dependent relativistic mean-field inference of the neutron-star equation of state with multi-messenger constraints
Wen-Jie Xie, Cheng-Jun Xia
We perform a Bayesian inference of the equation of state (EOS) of cold dense matter within a density-dependent relativistic mean-field (DD-RMF) model. An explicit inverse-mapping p…

Bayesian constraints on quark stars from multi-messenger observations
Wen-Jie Xie, Cheng-Jun Xia, Chen Zhang +1
We perform a systematic Bayesian analysis of quark star equations of state under current multimessenger constraints, investigating the impact of prior assumptions and extreme-mass…
