The exposure of the surface array in this part of the sky is already significantly larger than that of the fore-runner experiments. Our results do not support previous findings of localized excesses in the AGASA and SUGAR data. We set an upper bound on a point-like flux of cosmic rays arriving from the Galactic Centre which excludes several scenarios predicting sources of EeV neutrons from Sagittarius A. Also the events detected simultaneously by the surface and fluorescence detectors (the ‘hybrid’ data set), which have better pointing accuracy but are less numerous than those of the surface array alone, do not show any significant localized excess from this direction.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-01-31T13:51:28Z No. of bitstreams: 1 1-s2.0-S0927650506001733-main.pdf: 467867 bytes, checksum: 38bf82377cb2b9878fd73f260543e696 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-09-09T16:10:46Z (GMT) No. of bitstreams: 1 1-s2.0-S0927650506001733-main.pdf: 467867 bytes, checksum: 38bf82377cb2b9878fd73f260543e696 (MD5)Made available in DSpace on 2014-09-09T16:10:46Z (GMT).
