The Pierre Auger Observatory, being the largest air-shower experiment in the world, offers an unprecedented exposure to neutral particles at the highest energies. Since the start of data taking more than 18 years ago, various searches for ultra-high-energy (UHE, $E\gtrsim10^{17}\,\text{eV}$) photons have been performed: either for a diffuse flux of UHE photons, for point sources of UHE photons or for UHE photons associated with transient events like gravitational wave events. In the present paper, we summarize these searches and review the current results obtained using the wealth of data collected by the Pierre Auger Observatory.

  1. Readdressing the contribution of photonuclear reactions to the muon content of extensive air showers: a heuristic approach

    astro-ph.HE 2025-12 unverdicted novelty 6.0

    A new heuristic estimates photonuclear reactions' contribution to muon numbers in extensive air showers with roughly 10% absolute error over wide parameter ranges.
