                        Cosmic super particle-accelerators

Kivonatos ismertetés:
There exist very exotic places in the universe where extremely energetic, 
non-thermal processes are occurring. The abundant messengers from such objects 
are ultra-high cosmic ray particles, and nowadays also TeV gamma rays and 
astrophysical neutrinos are observed. There are exciting questions about where 
are the objects that can produce such particles, which processes are 
responsible for this, what exactly are those cosmic ray particles, and how do 
they reach Earth? By answering those fundamental questions we may learn about 
galactic and extra-galactic magnetic fields, the nature and structure of 
extremely violent astrophysical objects, the interaction of ultra-high energy 
particles with their environment, and even fundamental physics much beyond the 
reach of human-made particle accelerators like LHC.
