| Résumé : | Active galactic nuclei (AGN) are prime candidate sources of the high-energy, astrophysical neutrinos detected byIceCube. This is demonstrated by the real-time multimessenger detection of the blazar TXS 0506+056 and therecent evidence of neutrino emission from NGC 1068 from a separate time-averaged study. However, theproduction mechanism of the astrophysical neutrinos in AGN is not well established, which can be resolved viacorrelation studies with photon observations. For neutrinos produced due to photohadronic interactions in AGN, inaddition to a correlation of neutrinos with high-energy photons, there would also be a correlation of neutrinos withphotons emitted at radio wavelengths. In this work, we perform an in-depth stacking study of the correlationbetween 15 GHz radio observations of AGN reported in the MOJAVE XV catalog, and 10 yr of neutrino data fromIceCube. We also use a time-dependent approach, which improves the statistical power of the stacking analysis. Nosignificant correlation was found for both analyses, and upper limits are reported. When compared to the IceCubediffuse flux, at 100 TeV and for a spectral index o |
