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.
The Pierre Auger Collaboration finds an indication that some galaxies may be better partners of cosmic rays at the highest energies than others.
We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition.
