Unveiling Neutrinos' Secrets through Supernovae

Researchers at The Ohio State University have proposed using supernovae as a tool to study the mysterious properties of neutrinos, subatomic particles that rarely interact with normal matter. By analyzing the neutrino signal from Supernova 1987A, the researchers found that when neutrinos interact with themselves, they form a tightly coupled fluid that expands under relativistic hydrodynamics. This discovery could provide unprecedented sensitivity to neutrino self-interactions and shed light on the collective behavior of neutrinos and their impact on supernovae dynamics. However, further research is needed to determine if these changes are solely due to burst outflow or wind outflow.
