the hybrid nature of the pierre auger observatory provides for two independent ways to see cosmic rays. read more... observation of inclined eev air showers with the radio detector of the pierre auger observatory. 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. with the auger engineering radio array (aera), consisting of 150 detector stations on an area of 17 km2, we measure these signals in the 30 to 80 mhz band. for air showers arriving within 60° from the vertical, the radio emission illuminates only limited areas on the ground, of order a few hundred meters in diameter. consequently, radio signals are typically detectable only in a handful of aera radio detector stations for a given air shower.. dutch funding agency nwo provides 2.5 million € for the auger radio upgrade. the dutch organisation for scientific research (nwo) will fund a new antenna network at the pierre auger observatory. the research group cosmic ray research at radboud university and nikhef will receive 2.5 million € from the nwo large investment grant programme. july 31, 2018 – a new article on uhecrs has appeared in physics world: the pierre auger collaboration finds an indication that some galaxies may be better partners of cosmic rays at the highest energies than. inferences on mas* composition and tests of hadronic interactions from 0.3 to 100 eev using the water-cherenkov detectors of the pierre. we present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mas* composition. the pierre auger collaboration wins award of physicsworld.com: to the pierre auger observatory collaboration for showing that ultra-high-energy cosmic rays come from outside the milky way. a computer is used to construct a model of what happens in a high energy cosmic ray airshower. read more.. a model of the observatory layout was constructed, to be viewed interactively using google earth. read more..
