Future neutrino observatories, like the Deep Underground Neutrino Experiment (DUNE),
will be sensitive to supernovae and solar neutrinos of low energies. These neutrinos offer a unique
look inside stars and stellar explosions. Inside the DUNE liquid argon time projection chamber,
low-energy electron neutrinos will produce visible electrons. In this talk, we will present a
preliminary study of delta-rays that have similar energies to the electrons scattered by low-energy
astrophysical neutrinos. Unlike neutrinos, delta-rays are a well understood "standard candle."
Furthermore, they provide ample statistics, a valuable feature in the otherwise quiet underground
environment. We will outline how they can be used to calibrate DUNE's response to < 30 MeV
electrons in situ.
