Recent observations of two coherent radio pulses with the ANITA detector can be interpreted as steeply upward-going cosmic-ray showers with energies of a few tenths of an EeV and remain unexplained. The Pierre Auger Observatory has a large exposure to such upward propagating shower-like events, and has used 14 years of its Fluorescence Detector (FD) data to perform a generic search for such events with elevation angles greater than 20∘ from the horizon. Here this search is recast to constrain models generating high energy τ-leptons. For maximal flexibility, only the propagation, decay, and interactions of τ-leptons are treated in this analysis, meaning that the results are independent of the τ-production scenario.
