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!

A crystal clear place to study the skies

In the last few decades, Argentina and Chile have proven themselves prime spots for astronomical observation—a status that has been a boon in many ways for both countries.

How it all began

In 2006 Alan Watson wrote an article describing the birth of the Pierre Auger Project.

First antenna for the AugerPrime radio upgrade!

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.
