Signature of Collapsars as Sources for High-energy Neutrinos and $r$-process Nuclei

Gang Guo, Yong-Zhong Qian, Meng-Ru Wu

If collapsars are sources for both high-energy (HE) neutrinos and $r$-process nuclei, the profuse low-energy antineutrinos from $\beta$-decay of the newly-synthesized nuclei can annihi…
