Long-term calibration and validation of stability of the Auger Engineering Radio Array using the diffuse Galactic radio emission

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +356

The Auger Engineering Radio Array (AERA) measures radio emission from high-energy extensive air showers. Consisting of 153 autonomous radio-detector stations spread over \,km$^…

Quasi-constant time gap in multiple rings of elves

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +359

We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To…

Scaler data from the Pierre Auger Observatory as a proxy of solar activity

C. Taricco, I. Bizzarri, C. Dionese +1

Solar activity variations strongly impact the modulation of the flux of low-energy Galactic Cosmic Rays (GCRs) reaching the Earth. The secondary particles, which originate from the…

Search for UHE neutrinos from GRBs with the Pierre Auger Observatory

Yago Lema-Capeans

We report on the search for ultra-high-energy neutrinos from the prompt emission of gamma-ray bursts (GRBs) using Surface Detector (SD) data from Phase I of the Pierre Auger Observ…

Probing the mass composition of TeV cosmic rays with HAWC

J. C. Arteaga-Velázquez

In this contribution, we have investigated the energy spectra of the elemental mass groups of cosmic rays for the Light (H+He), medium (C+O) and heavy (Ne-Fe) components using the…

Search for Signatures of Dark Matter Annihilation in the Galactic Center with HAWC

R. Alfaro, C. Alvarez, A. Andrés +109

We conduct an indirect dark matter (DM) search in the Galactic Center, focusing on a square region within in Galactic longitude and latutide, using 2,865 days of da…
