X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
A Common Antimatter Response in AMS-02 Positrons and Antiprotons
Yi Yang
AMS-02 has reported a high-rigidity regularity that is difficult to interpret as a positron-only fact: above about , antiprotons, protons, and positrons have nearl…
A Possible Advanced Positron Signal in AMS-02 Measurements
Yi Yang
AMS-02 measurements show a striking separation between the characteristic energy scales of cosmic-ray electrons and positrons: the electron spectrum peaks near the ordinary retarde…
Universal Geometric Scaling in Cosmic Ray Spallation: Evidence of a Dynamical Causal Horizon from AMS-02
Yi Yang
The interpretation of high-precision cosmic ray spectra is fundamentally bottlenecked by uncertainties in fragmentation cross-sections. Traditional kinematic models, driven by phas…
Search for Axion-Like Particles in High-Magnetic-Field Pulsars with NICER
Yen-Jhen Liu, Yi Yang
Axion-like particles (ALPs) can couple to photons in strong magnetic fields, producing characteristic fluctuations in X-ray spectra. Using data from NASA's Neutron Star Interior Co…
Three-dimensional properties of a coronal shock and the longitudinal distribution of its related solar energetic particles
Yue Zhou, Li Feng, Guanglu Shi +6
This study aims to investigate the relationship between the spatial-temporal evolution of shock properties and the longitudinal dependence of SEP intensities and spectra. The shock…
