Search for ultra-high energy neutrino from TXS 0506+056

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.

Cosmic-ray anisotropies in right ascension

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

Directional sensitivity of the Pierre Auger Observatory to sources of UHE neutrinos

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.

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%.

Constraining the sources of UHECR with neutrinos

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

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.
