With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 10(17) eV and 10(20) eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 degrees in declination, with peak sensitivities at declinations around similar to -53 degrees and similar to +55 degrees, 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 flavours with no candidate events found in data taken between 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux 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, if they occur within the field of view corresponding to the zenith angle range between 60 degrees and 95 degrees where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.

Abstract

With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 10(17) eV and 10(20) eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 degrees in declination, with peak sensitivities at declinations around similar to -53 degrees and similar to +55 degrees, 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 flavours with no candidate events found in data taken between 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux 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, if they occur within the field of view corresponding to the zenith angle range between 60 degrees and 95 degrees where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.
