Abstract content

We present updated results for anisotropy searches in the direction of the Galactic centre at energies in the EeV range. We use data from the Pierre Auger Southern Observatory up to March, 2007. Present analyses are therefore based on a substantially larger data set than our previous published results. The larger statistics from the surface array allow for more precise measurements as a function of energy while the fluorescence detector data allow for the extension of our searches to energies below 1 EeV. In this paper, we test several scenarios for predicted sources of cosmic rays arriving from the Galactic center with energies between 0.1 and 10 EeV.
