Abstract: Neutrinos are unique cosmic messengers. Produced in the most extreme
environments in the Universe, they escape dense astrophysical regions
that are opaque to photons and carry information across vast
cosmological distances. Over the past decade, neutrino astronomy has
expanded dramatically, opening new windows on phenomena ranging from
core-collapse supernovae to the highest-energy cosmic accelerators.
I will present a broad view of neutrino astrophysics
across the energy spectrum — from MeV neutrinos emitted in stellar
explosions to TeV–PeV neutrinos observed from powerful extragalactic sources. I will emphasize the multimessenger perspective, highlighting the
connections between neutrinos, electromagnetic signals, cosmic rays and
gravitational waves. In particular, I will discuss how neutrinos and
gravitational waves together probe the physics of compact objects,
stellar collapse, and the dynamics of extreme cosmic environments.
I will also outline future developments in neutrino detection and
multimessenger astronomy, and how next-generation experiments will
deepen our understanding of fundamental physics and astrophysics alike.
