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.
Scientific Highlights
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.
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.
Ever since the existence of cosmic rays with individual energies of several Joules was established in the 1960s, speculation has raged as to whether cosmic particles of mean energy of 2 Joules are created in our Milky Way or in distant extragalactic objects.
