Inferences on Mass Composition and Tests of Hadronic Interactions from 0.3 to 100 EeV using the water-Cherenkov Detectors of the Pierre Auger Observatory

We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition.

"Physics World Top Ten Breakthrough of 2017"

The Pierre Auger Collaboration wins award of physicsworld.com: "To the Pierre Auger Observatory collaboration for showing that ultra-high-energy cosmic rays come from outside the Milky Way."

Obituary for Michael Hillas

It is our sad duty to announce that Michael Hillas, a great scientist and founder of modern high-energy astroparticle physics, passed away on November 26, 2017 at the age of 85.

New Spokespersons for the Pierre Auger Observatory


We are very happy to announce the election of our new spokespersons at the recent collaboration meeting of the Pierre Auger Observatory.

Calibration of the Logarithmic-Periodic Dipole Antenna (LPDA) Radio Stations at the Pierre Auger Observatory using an Octocopter


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.

Spectral Calibration of the Fluorescence Telescopes of the Pierre Auger Observatory


To estimate the energy of any cosmic ray event detected by the Pierre Auger Observatory, the detectors have to be calibrated.
