  The elusive nature of Dark Matter (DM) remains a mystery far from being
solved. A vast effort is dedicated to search for signatures of feeble DM
interactions with Standard Model particles. In this work, we explore the
signatures of axion DM boosted by interactions with Supernova neutrinos:
Neutrino-Boosted Axion DM ($\nu$BADM). We focus on $\nu$BADM converting into
photons in the Galactic magnetic field, generating a peculiar gamma-ray flux.
This signal falls in the poorly explored MeV energy range, that will be probed
by next generation gamma-ray missions. Once more, astrophysical searches might
act as a probe of fundamental physics, unveiling the nature and properties of
DM.
