Supernova neutrinos can boost dark matter particles, creating signals that vary over time and space in our galaxy. This study compares these local signals with the diffuse background from all past supernovae in the universe.

Why it matters: Understanding these signals helps refine dark matter detection strategies using supernova neutrinos.

The big picture: Local Milky Way signals vary significantly when dark matter is relativistic, while diffuse background dominates otherwise.

Stunning stat: The diffuse background from all past supernovae consistently outshines local signals unless dark matter becomes ultrarelativistic.

Quick takeaway: Diffuse supernova neutrino-boosted dark matter remains the primary detection target until a new galactic supernova occurs.
