30TH INTERNATIONAL COSMIC RAY CONFERENCE Test of hadronic interaction models with data from the Pierre Auger Observatory
نویسنده
چکیده
The Pierre Auger Observatory allows the measurement of both longitudinal profiles and lateral particle distributions of high-energy showers. The former trace the overall shower development, mainly of the electromagnetic component close to the core where the latter reflect the particle densities in the tail of the shower far away from the core and are sensitive to both the muonic and electromagnetic components. Combining the two complementary measurements, predictions of air shower simulations are tested. In particular the muon component of the tank signals, which is sensitive to hadronic interactions at high energy, is studied with several independent methods. Implications for the simulation of hadronic interactions at ultra-high energy are discussed.

Measurements of the Muon Content of UHECR Air Showers with the Pierre Auger Observatory
The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air showers (EAS), including measurements of the EAS particle content on ground which is sensitive to high-energy hadronic interactions. We present the results of several independent measurements of the EAS muon content ...

A wide range of atmospheric monitoring instruments is employed at the Pierre Auger Observatory : two laser facilities, elastic lidar stations, aerosol phase function monitors, a horizontal attenuation monitor, star monitors, weather stations, and balloon soundings. We describe the impact of analyzed atmospheric data on the accuracy of shower reconstructions, and in particular study the effect o...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Search for Coincidences in Time and Arrival Direction of Auger Data with Astro- physical Transients
The data collected by the Pierre Auger Observatory are analyzed to search for coincidences between the arrival directions of high-energy cosmic rays and the positions in the sky of astrophysical transients. Special attention is directed towards gamma ray observations recorded by NASA’s Swift mission, which have an angular resolution similar to that of the Auger surface detectors. In particular,...

The southern part of the Pierre Auger Observatory (PAO) is nearing completion in the province of Mendoza, Argentina. Since 2004 the instrument is used to take air shower data at the highest energies [1]. The energy threshold of the 3000 km2 surface array of 1600 particle detectors for high quality air shower reconstruction is about 3 . 10 eV. The 24 Auger fluorescence telescopes (FD), located i...
