A new method for the estimation of the "invisible" energy

This data-based method Improves the accuracy on the determination of the energy of cosmic rays with the Pierre Auger Observatory by 5%.

Cosmic-ray anisotropies in right ascension measured by the Pierre Auger Observatory

In a recent publication, the Pierre Auger Observatory has presented measurements of the large-scale cosmic-ray (CR) anisotropies in right ascension, using data collected by the surface detector array over more than 14 years, up to 31st August 2018. The dataset covers the energy range from ~0.03 EeV up to the highest detected energies.

Constraining the sources of UHECR with neutrinos

Most stringent limits so far to the diffuse flux of UHE neutrinos in the EeV energy range.

Daniela Mockler wins "Prize for best speaker"

At the BPS meeting in May 2019, Dr. Daniela Mockler was awarded the "Prize for best speaker". Congratulations!

Getting insights into the measured dipolar anisotropy

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.

What is the best match for an ultra energetic cosmic ray?

The Pierre Auger Collaboration finds an indication that some galaxies may be better partners of cosmic rays at the highest energies than others.
