History of UHECR production in Centaurus A
Cainã de Oliveira, Vitor de Souza
The origin of the UHECR continues to puzzle, however, an excess of detection in the direction of the radio galaxy Centaurus A (Cen A) raises the possibility of this object being th…
Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies
Júlia G. Mamprim, Guillermo Gambini, Luan B. Arbeletche +2
In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $Λ\…
Effect of the uncertainty in the hadronic interaction models on the estimation of the sensitivity of the Cherenkov Telescope Array
Michiko Ohishi, Luan Arbeletche, Vitor de Souza +6
Imaging Atmospheric Cherenkov Telescopes (IACTs) are ground-based indirect detectors for cosmic gamma rays with energies above tens of GeV. The major backgrounds for gamma-ray obse…
Revisiting the distance to the nearest UHECR source: Effects of extra-galactic magnetic fields
Rodrigo Guedes Lang, Andrew M. Taylor, Markus Ahlers +1
We update the constraints on the location of the nearest UHECR source. By analyzing recent data from the Pierre Auger Observatory using state-of-the-art CR propagation models, we r…
The optical depth including Lorentz invariance violation energy threshold shifts
Humberto Martínez-Huerta, Rodrigo G. Lang, Vitor de Souza
Lorentz invariance violation (LIV) introduced as a generic modification to particle dispersion relations can change the photon energy threshold of pair-production, which modifies t…
Astroparticle Physics Tests of Lorentz Invariance Violation
Rodrigo Guedes Lang, Vitor de Souza
Testing Lorentz invariance is essential as it is one of the pillars of modern physics. Moreover, its violation is foreseen in several popular Quantum Gravity models. Several author…
Search for correlations between the arrival directions of IceCube neutrino events and ultrahigh-energy cosmic rays detected by the Pierre Auger Observatory and the Telescope Array
The IceCube Collaboration, M. G. Aartsen, K. Abraham +863
This paper presents the results of different searches for correlations between very high-energy neutrino candidates detected by IceCube and the highest-energy cosmic rays measured…
An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462
Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…
A search for point sources of EeV photons
Pierre Auger Collaboration, A. Aab, P. Abreu +483
Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point…
