description: The IceCube Collaboration has observed a high-energy astrophysical neutrino flux and recently found evidence for neutrino emission from the blazar TXS 0506+056. However, the source or sources of most of the observed flux remains uncertain. Through-going muons produced by muon-neutrinos are ideal to search for point-like neutrino emission from astrophysical sources because their arrival direction can be resolved with an angular resolution $\leq1^\circ$. Here, an unbinned search for steady point-like neutrino sources is performed based on eight years of IceCube data measured between 2009 and 2017. Compared to previous searches, this search includes an improved event selection and reconstruction and it is optimized for point-like neutrino emission with the same flux-characteristics as the observed astrophysical muon-neutrino flux. The result is an improvement in flux sensitivity of ~35% assuming an $E^{-2}$ spectrum. The sensitivity on the muon-neutrino flux is at a level of $E^2 \mathrm{d} N /\mathrm{d} E = 3\cdot 10^{-13}\,\mathrm{TeV}\,\mathrm{cm}^{-2}\,\mathrm{s}^{-1}$. No new evidence for neutrino sources is found in a full sky scan and in an a priori candidate source list. Furthermore, no significant excesses above background are found from populations of sub-threshold sources. The implications of the non-observation for potential source classes are discussed.
