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.
On August 17, 2017 the LIGO and Virgo collaboration measured a gravitational wave originating from a binary neutron star merger.
