Resumen:
We present the results of an analysis of data recorded at the Pierre
Auger Observatory in which we search for groups of directionally-aligned
events (or multiplets) which exhibit a correlation between arrival
direction and the inverse of the energy. These signatures are expected
from sets of events coming from the same source after having been
deflected by intervening coherent magnetic fields. The observation of
several events from the same source would open the possibility to
accurately reconstruct the position of the source and also measure the
integral of the component of the magnetic field orthogonal to the
trajectory of the cosmic rays. We describe the largest multiplets found
and compute the probability that they appeared by chance from an
isotropic distribution. We find no statistically significant evidence
for the presence of multiplets arising from magnetic deflections in the
present data.
