Binary Neutron Star Mergers as Potential Sources for Ultra-High-Energy Cosmic Rays and High-Energy Neutrinos
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
Recent studies suggest that the most energetic cosmic rays, exceeding 100 EeV, may primarily consist of -process nuclei. This highlights binary neutron star mergers and collapsa…
Neutrino Oscillations in Core-Collapse Supernovae and Neutron Star Mergers
Lucas Johns, Sherwood Richers, Meng-Ru Wu
Accurate neutrino transport is crucial for reliably modeling explosive astrophysical events like core-collapse supernovae (CCSNe) and neutron star mergers (NSMs). However, in these…

Symmetry and bipolar motion in collective neutrino flavor oscillations
Zewei Xiong, Meng-Ru Wu, Yong-Zhong Qian
We identify a geometric symmetry on the two-flavor Bloch sphere for collective flavor oscillations of a homogeneous dense neutrino gas. Based on this symmetry, analytical solutions…
Signature of Collapsars as Sources for High-energy Neutrinos and -process Nuclei
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
If collapsars are sources for both high-energy (HE) neutrinos and -process nuclei, the profuse low-energy antineutrinos from -decay of the newly-synthesized nuclei can annihi…
