  "abstract": "We use 10 years of publicly available IceCube data to investigate the correlations between hight-energy neutrinos and various Fermi-LAT gamma-ray samples. This work considers the following gamma-ray samples:the third Fermi-LAT catalog of high-energy sources(3FHL), >100GeV Fermi-LAT events, LAT 12-year source catalog(4FGL), the fourth catalog of activate galactic nuclei(4LAC) and subsets of these samples. For each sample, both a single-source analysis and a joint likelihood analysis are performed. We find no indication that the sources in these samples produce significant high-energy neutrinos .From the null search result, we infer that each source population can produce no more than ~0.3%-27% (at the 95% confidence level) of the IceCube's diffuse neutrino flux. Since we are using a larger(10 years) dataset of IceCube neutrinos , the constriants are improved by a factor of ~2 compared to those based on 3 years of data.",
