Scientific Highlights

Results of a search of ultra-high energy neutrinos with the Pierre Auger Observatory from the powerful blazar TXS0506+056 at a redshift of 0.34 have been recently presented in a Journal article. The implications of the non-observation of neutrinos are compared to results obtained with the IceCube neutrino detector for three different search periods.

In a recent publication, the Pierre Auger Observatory has presented measurements of the large-scale cosmic-ray (CR) anisotropies in right ascension.

In the second paper of a series of two devoted to the search for Ultra-High Energy (UHE) neutrinos at the Pierre Auger Observatory, the Pierre Auger Collaboration has addressed the sensitivity of the Surface Detector array (SD) to steady and transient point sources of UHE neutrinos as a function of declination.

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

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

Extensive air showers, initiated in the Earth’s atmosphere by high-energy cosmic rays, emit pulsed radio signals with a typical duration of tens of nanoseconds.
