| contents | We present recent work on the Spectra of IceCube Neutrino (SIN) candidate sources project. We defined a selection of candidate neutrino sources by identifying blazars in the vicinity of IceCube's highest-energy neutrinos. We now want to shed light on these source candidates' nature, starting at their redshift, continuing with their black hole masses, their variability, and, for the first time, a combined photon-neutrino spectral energy distribution. We present their hybrid spectral energy distributions (combining photon and neutrino fluxes), investigate the sources' variability in the near-infrared, optical, X-ray, and $γ$-ray bands, and compare the variability with a blazar sample of non-candidate sources. Furthermore, we search for flares at the arrival time of the high-energy neutrinos. |
