Discriminating potential astrophysical sources of the highest energy cosmic rays with the Pierre Auger Observatory
THE PIERRE AUGER COLLABORATION (AUTOR 434 DE 474); M. TUEROS
Conferencia; 31st International Cosmic Ray Conference; 2009
We compare the distribution of arrival directions of the highest energy cosmic rays detected by the Pierre Auger Observatory from 1 January2004 to 31 March 2009 with that of populations of potential astrophysical sources. For this purpose, we use several complementary statistical tests allowing one to describe and quantify the degree of compatibility between data and a given catalogue of sources. We applied these tests to active galactic nuclei detected in X-rays by SWIFT-BAT and to galaxies found inthe HI Parkes and in the 2 Micron All-Sky Surveys.
