Challenges in Binary Pulsar Timing Detection of Dark Matter Subhalos
Zheng-Long Wang, Zi-Qing Xia, Yue-Lin Sming Tsai +1
Recently, binary pulsar timing has been proposed as a viable probe of dark matter subhalos with masses of in the solar neighborhood. We present a comprehensi…
The Non-parametric Equation of State Realizes a Generalized Quark-Hadron Crossover
Yong-Jia Huang, Shao-Peng Tang, Yi-Zhong Fan
We propose a non-parametric approach to construct the statistical equation of state (EOS) continuously from the nuclear crust to the asymptotic-freedom regime. The combined require…
The Very Late Time Afterglow of GW170817 Favors a Wobbling Jet
Hao Wang, Ore Gottlieb, Aman Katira +4
GW170817 remains the only binary neutron star merger detected through multimessenger emission. Its afterglow has been monitored for nearly a decade, offering an unprecedented oppor…
Secondary-Mass Features improve Spectral-Siren Constraints
Yin-Jie Li, Yi-Ying Wang, Yuan-Zhu Wang +2
Gravitational-wave (GW) signals from compact binary coalescences (CBCs) enable independent measurements of the Hubble constant \(H_0\) via the spectral siren method, which critical…
Milky Way Dynamics Favor Dark Matter over Modified Gravity Models
Zheng-long Wang, Yue-Lin Sming Tsai, Lan Zhang +5
Modified gravity theories such as Modified Newtonian Dynamics (MOND) and Scalar-Tensor-Vector Gravity (STVG) have been proposed as alternatives to dark matter, but decisive tests h…
Self-Interacting Dark Matter with Mass Segregation: A Unified Explanation of Dwarf Cores and Small-Scale Lenses
Daneng Yang, Yi-Zhong Fan, Siyuan Hou +1
In two-component self-interacting dark matter (SIDM) models with inter-species interactions, mass segregation arises naturally from collisional relaxation, enhancing central densit…
