Most stringent limits so far to the diffuse flux of UHE neutrinos in the EeV energy range.
Scientific Highlights
The Pierre Auger Collaboration measured a dipolar anisotropy in the arrival-direction distribution of the cosmic rays with energies in excess of 8x1018 eV, finding that the flux is about
6.5% larger than the average in one direction of the sky and it is correspondingly smaller in the opposite direction.
The Pierre Auger Collaboration finds an indication that some galaxies may be better partners of cosmic rays at the highest energies than others.
We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition.
In a recent calibration campaign at the Pierre Auger Observatory, the directional and frequency characteristics of the radio stations equipped with logarithmic periodic dipole antennas (LPDAs) have been determined using a remotely piloted octocopter.
To estimate the energy of any cosmic ray event detected by the Pierre Auger Observatory, the detectors have to be calibrated.
