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 60o and 95o where the SD of the Pierre Auger Observatory is most sensitive to neutrinos.ELETTRONICOenLimits on point-like sources of ultra-high-energy neutrinos with the Pierre Auger ObservatoryArticle10.1088/1475-7516/2019/11/0042-s2.0-85080059488000507259700001https://iopscience.iop.org/article/10.1088/1475-7516/2019/11/0042019JCAP...11..004AFIS/05 - ASTRONOMIA E ASTROFISICA
