“…The flux pattern in the sky is more intense in a hot-spot region around the Galactic center; it provides therefore clear signatures. On the other hand, the non-observation of UHE photons reported in [30][31][32] enables one to constrain the all-sky flux observed over the solid angle ΔΩ, ⟨𝐽 DM,𝛾 (𝐸, n)⟩ = ∫ ΔΩ dn 𝐽 DM,𝛾 (𝐸, n)/ΔΩ, and thus to constrain the unknown 𝑀 𝑋 and 𝜏 𝑋 parameters.…”

Using data collected at the Pierre Auger Observatory, we search for signatures of instanton-induced processes that would provide evidence of super-heavy particles decaying in the Galactic halo. Such particles could have been produced sufficiently during the post-inflationary epoch to match the relic abundance of dark matter inferred today. The non-observation of these signatures allows us to probe the instanton strength and to derive a bound, the best ever obtained from instanton-mediated processes, on the reduced coupling constant of gauge interactions in the dark sector: 𝛼 𝑋 ≲ 0.09, for 10 9 ≲ 𝑀 𝑋 /GeV < 10 19 . *** 27th European Cosmic RaySymposium -ECRS *** *** 25-29 July 2022 *** *** Nĳmegen, the Netherlands ***

“…No photon has yet been conclusively detected by the Pierre Auger Observatory, leading to the most restrictive upper limits on the photon flux at the highest energies [18][19][20]. Multivariate analyses based on SD and FD data was perfomed in the all events with zenith angle between 30 • and 60 • measured from 1 January 2004 to 30 June 2018.…”

Lorentz invariance violation (LIV) is often described by dispersion relations of the formwith delta different based on particle type i, with energy E, momentum p and rest mass m. Kinematics and energy thresholds of interactions are modified once the LIV terms become comparable to the squared masses of the particles involved. Thus, the strongest constraints on the LIV coefficients δ i,n tend to come from the highest energies. At sufficiently high energies, photons produced by cosmic ray interactions as they propagate through the Universe could be subluminal and unattenuated over cosmological distances. Cosmic ray interactions can also be modified and lead to detectable fingerprints in the energy spectrum and mass composition observed on Earth. The data collected at the Pierre Auger

“…While cosmic rays have played a small role in real-time multi-messenger alerts, the Pierre Auger Collaboration is implementing a new data stream that will send to AMON ultra-high energy photon candidates. This stream will contain events with energies above 1 EeV that satisfy a certain sub-threshold photon selection based on a Multivariate analysis [99].…”

The observation of electromagnetic counterparts to both high energy neutrinos and gravitational waves marked the beginning of a new era in astrophysics. The multi-messenger approach allows us to gain new insights into the most energetic events in the Universe such as gamma-ray bursts, supernovas, and black hole mergers. Real-time multi-messenger alerts are the key component of the observational strategies to unravel the transient signals expected from astrophysical sources. Focusing on the high-energy regime, we present a historical perspective of multi-messenger observations, the detectors and observational techniques used to study them, the status of the multi-messenger alerts and the most significant results, together with an overview of the future prospects in the field.
