Much of what is known about this flux comes from a small event sample of high neutrino purity, good energy resolution, but large angular uncertainties. In searches for point-like sources, on the other hand, the best performance is given by using large statistics and good angular reconstructions. Track-like muon events produced in neutrino interactions satisfy these requirements. We present here the results of searches for point-like sources with neutrinos using data acquired by the IceCube detector over 7 yr from 2008 to 2015. The discovery potential of the analysis in the northern sky is now significantly below ${E}_{\nu }^{2}d\phi /{{dE}}_{\nu }$ = 10−12 TeV cm−2 s−1, on average 38% lower than the sensitivity of the previously published analysis of 4 yr exposure. No significant clustering of neutrinos above background expectation was observed, and implications for prominent neutrino source candidates are discussed. en_US dc.publisher American Astronomical Society en_US dc.subject Astroparticle physics en_US dc.subject Galaxies: active en_US dc.subject Neutrinos en_US dc.title All-sky Search for Time-integrated Neutrino Emission from Astrophysical Sources with 7 yr of IceCube Data en_US dc.type Article en_US kusw.kuauthor Besson, David Zeke kusw.kudepartment Physics and Astronomy en_US dc.identifier.doi 10.3847/1538-4357/835/2/151 en_US kusw.oaversion Scholarly/refereed, publisher version en_US kusw.oapolicy This item meets KU Open Access policy criteria. en_US dc.rights.accessrights openAccess en_US
