Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346

Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…

Search for active-sterile neutrino transitions using Pierre Auger Observatory data

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348

We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…

Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347

Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…

Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357

Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…

Investigating IceCube Neutrino Alerts with the HAWC -Ray Observatory

The HAWC Collaboration, R. Alfaro, C. Alvarez +95

Neutrino emission from astrophysical sources has long been considered a signature of cosmic-ray acceleration. The IceCube neutrino observatory has observed a diffuse flux of TeV-Pe…

Improved Heavy Dark Matter Annihilation Search from Dwarf Galaxies with HAWC

A. Albert, R. Alfaro, C. Alvarez +103

Understanding dark matter's elusive nature is crucial for the framework of particle physics and expanding the Standard Model. This analysis utilizes the High Altitude Water Cherenk…
