Resumen:
With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 1017 eV and 1020 eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 in declination, with peak sensitivitiesat declinations around 53 and +55, and an unmatched sensitivity for arrival directions in the Northern hemisphere. A search has been performed for highly-inclined air showers induced by neutrinos of all avours with no candidate events found in data takenbetween 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino ux from point-like steady sources have been derived as a function of source declination. An unrivaled sensitivity is achieved in searches for transient sources with emission lasting over an hour or less, ifthey occur within the eld of view corresponding to the zenith angle range between 60 and 95 where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.
