A thorough search of the sky exposed at the Pierre Auger Cosmic Ray Observatory reveals no statistically significant excess of events in any small solid angle that would be indicative of a flux of neutral particles from a discrete source. The search covers from −90◦ to +15◦ in declination using four different energy ranges above 1 EeV (10 eV). The method used in this search is more sensitive to neutrons than to photons. The upper limit on a neutron flux is derived for a dense grid of directions…

Cosmic-ray astronomy at the highest energies with ten years of data of the Pierre Auger observatory

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

Different approaches to determine the composition of the ultra-high energy cosmic rays in the Pierre Auger Observatory

The motivation of this PhD thesis is to improve the capabilities to determine the mass composition of the ultra-high energy cosmic rays in the Pierre Auger Observatory. The measure of their mass

Reviewing the latest results from the Pierre Auger Observatory

The Pierre Auger Observatory was built to help unveil the properties of ultra-high energy cosmic rays with energies from 1017 to 1020 eV. In this paper we review the latest results obtained from data

Constraining the sources of ultra-high energy cosmic rays with multi-messenger data

Ultra-high energy cosmic rays (UHECRs) are cosmic rays with energy exceeding 10¹⁸ electronvolts. The sources of these particles remain unknown despite decades of research. This thesis presents a

Neutrino Lighthouse at Sagittarius A

We investigate whether a subset of high-energy events observed by IceCube may be due to neutrinos from Sagittarius A*. We check both spatial and temporal coincidences of IceCube events with other
