WebFinally, the energies associated with such UHECR's often violate the so-called "GZK bound" which provides a theoretical upper limit on the energies that cosmic rays may have. Understanding how such UHECR's manage to violate … WebJul 3, 2007 · Meanwhile, researchers working with HiRes, which stopped taking data in last year, say that they have definitely observed the GZK cutoff in their final spectrum of cosmic rays. "It looks very much like what everyone has been predicting," says Pierre Sokolsky of the University of Utah in Salt Lake City. "It's the classic GZK cutoff."

N. Kersting. The maximum distance bound for ultrahigh energy cosmic rays (UHECR) with energies above the Greisen-Zatsepin-Kuzmich cutoff relaxes significantly if there is some mechanism that forces UHECR to propagate in discrete intervals, rather than continuously, through intergalactic space.

The Greisen–Zatsepin–Kuzmin limit (GZK limit or GZK cutoff) is a theoretical upper limit on the energy of cosmic ray protons traveling from other galaxies through the intergalactic medium to our galaxy. The limit is 5×10 eV (50 EeV), or about 8 joules (the energy of a proton travelling at ≈ … See more The limit was independently computed in 1966 by Kenneth Greisen, Georgiy Zatsepin, and Vadim Kuzmin based on interactions between cosmic rays and the photons of the cosmic microwave background radiation (CMB). … See more In November 2007, researchers at the Pierre Auger Observatory announced that they had evidence that UHECRs appear to come from the See more • Ultra-high-energy cosmic ray – Cosmic-ray particle with a kinetic energy greater than 10 eV See more A number of observations have been made by the largest cosmic-ray experiments Akeno Giant Air Shower Array, High Resolution Fly's Eye Cosmic Ray Detector, the Pierre Auger Observatory and Telescope Array Project that appeared to show cosmic rays … See more A suppression of the cosmic-ray flux that can be explained with the GZK limit has been confirmed by the latest generation of cosmic-ray observatories.
