Description
The Pierre Auger Observatory, while primarily designed to detect ultra-high-energy cosmic rays (UHECRs), possesses a high sensitivity to neutrinos with energies exceeding 100 PeV. By identifying the unique characteristics of highly inclined air showers, i.e., those with zenith angles above 60 degrees, the Observatory efficiently detects neutrinos of all flavors. This presentation reviews the current status of neutrino searches at Auger Observatory. The establishment of stringent upper limits on the neutrino flux from both diffuse and point-like sources has placed significant constraints on EeV-energy neutrino production models and the fundamental properties of UHECR sources. Furthermore, the Observatory has achieved high sensitivity in searches for transient events. Finally, we address the search for upward-going air showers, motivated by the "anomalous" radio pulses reported by the ANITA experiment. Based on the significantly larger exposure to upward-going showers at the Auger Observatory, the non-observation of such events severely constrains the upward-going shower explanation of the ANITA events for showers originating from known particle decays or interactions.
