Book excerpt: The Pierre Auger Observatory, located on a vast, high plain in western Argentina, is the world's largest cosmic ray observatory. The objectives of the Observatory are to probe the origin and characteristics of cosmic rays above $10$̂ eV and to study the interactions of these, the most energetic particles observed in nature. The Auger design features an array of 1660 water-Cherenkov particle detector stations spread over 3000 km$2̂$ overlooked by 24 air fluorescence telescopes. In addition, three high elevation fluorescence telescopes overlook a 23.5 km$2̂$, 61 detector infill array. The Observatory has been in successful operation since completion in 2008 and has recorded data from an exposure exceeding 40,000 km$2̂$ sr yr. This paper describes the design and performance of the detectors, related subsystems and infrastructure that make up the Auger Observatory.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying the sources of the ultra-high energy cosmic rays (UHECRs, above 10^{18} eV), the most energetic particles known in the universe, would be an important leap forward for both the astrophysics and particle physics knowledge. However, developing a cosmic-ray astronomy is arduous because magnetic fields, that permeate our Galaxy and the extra-Galactic space, deflect cosmic rays that may lose the directional information on their sources. This problem can be reduced by studying the highest energy end of the cosmic ray spectrum. Indeed, magnetic field deflections are inversely proportional to the cosmic ray energy. Moreover, above 4x10^{19} eV, cosmic rays interact with cosmic photon backgrounds, losing energy. This means that the sources of the highest energy cosmic rays observed on Earth can be located only in the nearby universe (200 Mpc or less). The largest detector ever built for detecting cosmic rays at such high energies is the Pierre Auger Observatory, in Argentina. It combines a 3000 km^2 surface array of water Cherenkov detectors with fluorescence telescopes to measure extensive air showers initiated by the UHECRs. This thesis was developed inside the Auger Collaboration and was devoted to study the highest energy events observed by Auger, starting from the selection and reconstruction up to the analysis of their distribution in the sky. Moreover, since the composition at these energies is unknown, we developed a method to select proton-like events, since high Z cosmic rays are too much deflected by magnetic fields to be used for cosmic-ray astronomy.

Book Synopsis Searching for Beyond the Standard Model Physics at the Pierre Auger Cosmic Ray Observatory by : Mason Buchanan

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the course of three flights, the Antarctic Impulsive Transient Antenna (ANITA) appeared to detect two cosmic ray events from the Earth below, referred to as "Sub-EeV Earth-emergent Cosmic Rays" (SEECRs). This paper turns to the largest cosmic ray detector in the world, the Pierre Auger Observatory, to search for SEECR candidates, set limits on their incidence, and compare the results to the ANITA detections. 10% of the detections made by the Pierre Auger fluorescence detectors (FDs) made from 2007 to 2018 were considered. To isolate SEECR candidates, five cuts were made to the Auger data: the first used computer vision techniques to remove background produced by the Auger laser facilities, the second defined a minimum number of triggered pixels in the FD camera, the third defined a minimum shower zenith angle, the fourth defined a minimum track length on the FD camera, and the fifth defined a minimum probability of the fit of the shower reconstruction. 7 (+8, -4) detections remain after these cuts. Simulations of upgoing events and past exposure comparisons predict 49 SEECR events in the examined data for consistency with ANITA, over 5[sigma] above the observed value. Similar results in the full Pierre Auger data set would widen this discrepancy further.

Book Synopsis Arrival Direction Probabilities of Ultra High Energy Cosmic Rays with the Pierre Auger Observatory and Progress Toward an In-situ Cross-calibration of Auger and Telescope Array Surface Detector Stations by : Sean P. Quinn
Download or read book Arrival Direction Probabilities of Ultra High Energy Cosmic Rays with the Pierre Auger Observatory and Progress Toward an In-situ Cross-calibration of Auger and Telescope Array Surface Detector Stations written by Sean P. Quinn and published by . This book was released on 2018 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin and nature of ultra-high energy cosmic rays is an open question in astrophysics since their discovery in the 1960s. Observed energies of these primary particles can approach greater than 10x the center of mass energies achieved at modern collider facilities, and there is presently no consensus for an astrophysical mechanism capable of reaching these energies. The Pierre Auger Observatory is the world's largest cosmic ray observatory, spanning ~3,000 km2, dedicated to this problem. After initial acceleration, the primary trajectory from source to solar system is not rectilinear due to magnetic deflection. This dissertation investigates how uncertainties of a modern galactic magnetic field model translate into arrival direction uncertainties for E>50 EeV events using a sensitivity analysis approach. In most cases it's found that uncertainties from B-field model dominate compared to observation systematic errors. Furthermore, the angular extent of 1s arrival direction contours is found to enclose many potential astrophysical objects, making it difficult to isolate individual sources. Implications for anisotropy studies are also briefly discussed.To enable full-sky coverage, Auger data can be combined with the Telescope Array Project, a similar array operating in the northern hemisphere. In both experiments most data are generated from the surface-detector (SD) array. The TA and Auger experiments use different SD station designs, giving them different sensitivities to extensive air-shower components. We seek to understand and cross-validate these complementary detectors on a hardware level using an in-situ approach to observe the same air showers. We describe the technical details associated with installing the detectors, data acquisition, and analysis of signals for this first stage of the Auger@TA project. Integrated signals are compared to a collection of models, and in general are found to agree with expectations. For a subsample of events air-shower parameters are available, and a sophisticated simulation is run to predict the expected response of the two detectors, which is compared to observed data. These simulations appear to show some discrepancy. Characterizing and understanding the discrepancies will be important for taking full advantage of future planned upgrades to both experiments, especially in the context of atomic composition measurements.
