SUMMARY:Neutrinos in the Universe\, Physics Department Colloquium\, Ce
 cilia Lunardini\, Arizona State University
DESCRIPTION:Neutrinos are unique cosmic messengers. Produced in the mo
 st extreme
\nenvironments in the Universe\, they escape dense astrophy
 sical regions
\nthat are opaque to photons and carry information acros
 s vast
\ncosmological distances. Over the past decade\, neutrino astro
 nomy has
\nexpanded dramatically\, opening new windows on phenomena ra
 nging from
\ncore-collapse supernovae to the highest-energy cosmic acc
 elerators.
\n
\nI will present a broad view of neutrino astrophysics
\
 nacross the energy spectrum — from MeV neutrinos emitted in stellar

 \nexplosions to TeV–PeV neutrinos observed from powerful extragalact
 ic sources. I will emphasize the multimessenger perspective\, highligh
 ting the
\nconnections between neutrinos\, electromagnetic signals\, c
 osmic rays and
\ngravitational waves. In particular\, I will discuss h
 ow neutrinos and
\ngravitational waves together probe the physics of c
 ompact objects\,
\nstellar collapse\, and the dynamics of extreme cosm
 ic environments.
\n
\nI will also outline future developments in neutr
 ino detection and
\nmultimessenger astronomy\, and how next-generation
  experiments will
\ndeepen our understanding of fundamental physics an
 d astrophysics alike.
