Analysis of blazar spectral energy distributions with SOPRANO

The recently reported association between the blazar TXS 0506+056 and high energy neutrinos by the IceCube experiment provided the possibility to perform the first multi-wavelength and multi-messenger analysis. The interpretation of this data set requires detailed spectral predictions, which can only be obtained numerically by solving the multi-species kinetic equations. To this end, we developed the code SOPRANO (Simulator Of Processes in Relativistic AstroNomical Objects). In this talk, I will first report on the development and capabilities of SOPRANO, and then, I will present recent results obtained with SOPRANO in the context of blazars SED.
