Jezik: Angleški jezik Vrsta gradiva: Neznano Tipologija: 1.08 - Objavljeni znanstveni prispevek na konferenci Organizacija: UNG - Univerza v Novi Gorici Opis: The Auger Engineering Radio Array (AERA) is an array of 153 radio antennas spanning an area of 17 sq. km, currently the largest of its kind, that probes the nature of ultra-high energy cosmic rays at energies around the transition from Galactic to extra-galactic origin. It measures the MHz radio emission of extensive air showers produced by cosmic rays hitting our atmosphere. The elemental composition of cosmic rays is a crucial piece of information in determining what the sources of cosmic rays are and how cosmic rays are accelerated. This composition can be obtained from the mass-sensitive parameter Xmax, the depth of the shower maximum. We reconstruct Xmax with a likelihood analysis by comparing the measured radio footprint on the ground to an ensemble of footprints from Monte-Carlo CORSIKA/CoREAS air shower simulations. We compare our Xmax reconstruction with fluorescence Xmax measurements on a per-event basis, a setup unique to the Pierre Auger Observatory, and show the methods to be compatible. Furthermore, we extensively validate our reconstruction by identifying and correcting for systematic uncertainties. We determine the resolution of our method as a function of energy and reach a precision better than 15 g/cm[sup]2 at the highest energies. With a bias-free set of around 600 showers, we find a light to light-mixed composition at energies between 10[sup]17.5 to 10[sup]18.8 eV, also in agreement with Auger fluorescence measurements.
