Large-scale Cosmic-Ray Anisotropies above 4 EeV Measured by the Pierre Auger Observatory
We present a detailed study of the large-scale anisotropies of cosmic rays with energies above 4 EeV measured using the Pierre Auger Observatory. For the energy bins [4, 8] EeV and E >= 8 EeV, theExpand

An Indication of Anisotropy in Arrival Directions of Ultra-high-energy Cosmic Rays through Comparison to the Flux Pattern of Extragalactic Gamma-Ray Sources
A new analysis of the data set from the Pierre Auger Observatory provides evidence for anisotropy in the arrival directions of ultra-high-energy cosmic rays on an intermediate angular scale, which isExpand

Features of the Energy Spectrum of Cosmic Rays above 2.5×10^{18}  eV Using the Pierre Auger Observatory.
We report a measurement of the energy spectrum of cosmic rays above 2.5×10^{18}  eV based on 215 030 events. New results are presented: at about 1.3×10^{19}  eV, the spectral index changes fromExpand

The photo-disintegration of $^4$He on the cosmic microwave background is less severe than earlier thought
We thoroughly study the photo-disintegration of $^4$He on the cosmic microwave background using the most recent cross-section data both from the inclusive measurement observing the analog of theExpand

Hunting for superheavy dark matter with the highest-energy cosmic rays
In 15 years of data taking the Pierre Auger Observatory has observed no events beyond $10^{11.3}$ GeV. This null result translates into an upper bound on the flux of ultrahigh-energy cosmic raysExpand

$H_0$ tension and the String Swampland
[Abridged] We realize the Agrawal-Obied-Vafa (AOV) swampland proposal of fading dark matter by the model of Salam-Sezgin and its string realization of Cvetic-Gibbons-Pope. The model describes aExpand
