IceCube: the High-energy Universe and Multimessenger Astrophysics with 
Neutrinos

Kivonatos ismertetés:
Astrophysical processes that produce the observed energetic cosmic particles 
(up to 10^20 eV) and high-energy gamma radiation involve extreme non-thermal 
acceleration, strongly constraining the list of possible sources. Nevertheless,
the origin of the most energetic cosmic rays, and the electromagnetic emission
mechanism in extreme sources such as gamma-ray bursts, are currently unknown. 
Neutrinos may well be the silver bullet to unravel these processes. They can 
reveal the hadronic nature of the emission, and due to their weak interaction 
they lead right back to the source. The IceCube  neutrino observatory at the 
South Pole has recently discovered a cosmic flux of TeV-PeV neutrinos, making 
the first step in lifting the curtain on cosmic particle accelerators. I will 
discuss recent  multimessenger observational developments, and source 
candidates in the high-energy universe. I will describe plans and capabilities 
for the next-generation neutrino detector IceCube-Gen2.
