INVESTIGATING THE ORIGINS OF UHECRS USING THE PIERRE AUGER OBSERVATORY AND PALEO-DETECTORS
… is the toe of the ultra-high energy cosmic ray (UHECR) spectrum, above ≈ 50 EeV. The potential for small magnetic deflections at these energies is coupled with the presence of flux suppression, which may be a sign of the sources’ maximum acceleration potential or may have an explanation for the …

Extreme universe space observatory on a super pressure balloon II fluorescence telescope on the ground and (briefly) in the air, The
… aimed to measure ultra-high energy cosmic ray (UHECR) induced extensive air showers (EAS) via nitrogen fluorescence by observing a large volume of atmosphere from above. In the years prior to launch, the design of the FT was informed by extensive end-to-end simulations of EAS and the detector …

Analisi degli spettri di particelle neutre prodotte a piccolo angolo con l’esperimento LHCf a LHC
… i raggi cosmici ad altissima energia (UHECR), sono stati oggetto di studi approfonditi a causa della loro rilevanza per l'astrofisica e la fisica delle particelle. Sebbene siano stati compiuti progressi sostanziali attraverso esperimenti a terra, come gli osservatori Pierre Auger e …

Design, Implementation and First Results of the ANITA-HiCal Experiment
… Radio detection of ultra-high energy cosmic ray (UHECR) extensive air showers (EAS) above the Antarctic continent has been demonstrated by the four flights of the ANITA experiment. The majority of the detected events were received as reflections from the ice surface. In order to reconstruct the …

Using power spectra to look for anisotropies in ultra-high energy cosmic ray distributions
… compositions of ultra-high energy cosmic rays (UHECR) remains a mystery to this day. The Pierre Auger Observatory (PAO) is being constructed now in the hopes that it will help solve this mystery by detecting more UHECR than any previous experiment. In this dissertation, I will discuss this …

Propagation of Ultra-High Energy Cosmic Rays and anisotropy studies with the Pierre Auger Observatory: the multiscale approach
… directions of ultra-high energy cosmic rays (UHECRs). The clustering of such events, collected by the Pierre Auger Observatory, is used to infer the nature of sources and their density, as well as other physical unknowns. Results are based on the comparison between real and simulated data. …

FROM DATA PRODUCTION TO SEARCH FOR GALACTIC COSMICRAY SOURCES WITH THE PIERRE AUGER OBSERVATORY
… investigates ultra-high-energy cosmic rays (UHECRs), the most energetic particles known in the Universe. Despite decades of research, their origins remain elusive. These particles are detected through extensive air showers, cascades of secondary particles produced when UHECRs interact with …

Design And Development Of An Autonomous Radar Receiver For The Detection Of Ultra High Energy Cosmic Rays
The detection of ultra-high energy cosmic rays is constrained by their flux, requiring detectors with apertures of hundreds or even thousands of square kilometers and close to one hundred percent duty cycle. The sheer scale that would be required of conventional detectors, to acquire sufficient …
