We propose to continue and expand on the association between IceCube neutrinos and astrophysical counterparts by studying from all angles a unique set of blazars. We will secure their optical spectra to determine the redshifts and characterize the sources, model their spectral energy distributions, and derive the expected neutrino emission. We will also analyse all new IceCube alerts by means of a brand-new multi-messenger pipeline and improve our understanding of the blazar population by updating the ‘blazar simplified view' simulation. Moreover, since we and others have shown that blazars cannot be the whole story, we will also explore other likely populations including active galactic nuclei outflows, star-forming galaxies, and Galactic sources.
