30TH INTERNATIONAL COSMIC RAY CONFERENCE Systematic study of atmosphere-induced influences and uncertainties on shower re- construction at the Pierre Auger Observatory
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 کاملAnisotropy studies of ultra - high energy cosmic rays as observed by the High Resolution Fly ’ s Eye ( HiRes )
Although the existence of cosmic rays with energies extending to 320 EeV has been confirmed , their origin remains one of the most important questions in particle astrophysics research today. The High–Resolution Fly’s Eye (HiRes) is the largest aperture detector currently collecting data from ultra-high energy cosmic ray events. We present for the first time anisotropy studies from monocular an...
متن کاملMolecular Clouds as Cosmic-ray Barometers
It is generally assumed that the flux of cosmic-rays observed at the top of the Earth’s atmosphere is representative of the flux in the Galaxy at large. The advent of high sensitivity, high resolution γ-ray detectors, together with a knowledge of the distribution of the atomic hydrogen and especially of the molecular hydrogen in the Galaxy on sub-degree scales, as provided by the NANTEN survey,...
متن کاملSimulation Calibration of an Extensive Air Shower array, by a logged data set of its small prototype
Alborz observatory is an EAS array in the heights of Alborez mountain chain near Tehran. For the development of the array, more number of detectors is inevitable. The managing the financial resources and achieving the highest efficiency of the array is important for the project. Therefore, Water Cherenkov Detectors has been used for 9 months in the same way as the previous experiment with Scint...
متن کاملThe Lidar System of the Pierre Auger Observatory
The Pierre Auger Observatory in Malargüe, Argentina, is designed to study the origin of ultrahigh energy cosmic rays with energies above 1018 eV. The energy calibration of the detector is based on a system of four air fluorescence detectors. To obtain reliable calorimetric information from the fluorescence stations, the atmospheric conditions at the experiment’s site need to be monitored contin...
