Since the first detection of a cosmic ray event with energy above 10 20 eV in 1962, their nature and origin remain unknown. ... A new generation cosmic ray detector, the Pierre Auger Observatory, has been designed to study cosmic rays with energy above 10 18 eV and answer the crucial questions of ultra high energy cosmic ray physics. ...

... GOODS unites extremely deep observations from NASA's Great Observatories, Spitzer , Hubble , and Chandra , ESA's Herschel and XMM-Newton , and from the most powerful ground-based facilities, to survey the distant universe to the faintest flux limits across the electromagnetic spectrum. ... The space-based observations are complemented by ground-based imaging and spectroscopy, including extensive commitments of ESO and NOAO observing time. ... 2010-04-10: Deep VLA 1.4 GHz data for GOODS-North . ...

... New results from Auger, however, indicate that 12 of 15 ultra high energy cosmic rays have sky directions statistically consistent with the positions of nearby active galactic nuclei . ... The Auger results also indicate that the highest energy cosmic rays are protons, since the electric charge of higher energy nuclei would force the Milky Way Galaxy 's magnetic field to deflect and effectively erase progenitor source direction. ...
