Measurements of the Muon Content of UHECR Air Showers with the Pierre Auger Observatory

چکیده

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 on ground in Auger data at a primary energy of 10 EeV. We discuss implications on high-energy hadronic interaction models and cosmic ray composition.

The Fluorescence Detector of the Pierre Auger Observatory - a Calorimeter for UHECR

The Pierre Auger Observatory is a hybrid detector for ultrahigh energy cosmic rays (UHECR) with energies above 1018.5 eV. Currently the first part of the Observatory nears completion in the southern hemisphere in Argentina. One detection technique uses over 1600 water Cherenkov tanks at ground where samples of secondary particles of extensive air showers (EAS) are detected. The second technique...

30TH INTERNATIONAL COSMIC RAY CONFERENCE Test of hadronic interaction models with data from the Pierre Auger Observatory

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 electromagn...

The Uhecr Spectrum Measured at the Pierre Auger Observatory and Its Astrophysical Implications Uhe Cosmic Ray Energy Spectrum

The Southern part of the Pierre Auger Observatory is nearing completion, and has been in stable operation since January 2004 while it has grown in size. The large sample of data collected so far has led to a significant improvement in the measurement of the energy spectrum of UHE cosmic rays over that previously reported by the Pierre Auger Observatory, both in statistics and in systematic unce...

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...
