Nonthermal SED derived from our jet model. We considered the following radiative processes: for protons, synchrotron emission and proton-proton collisions with the cold protons of the jet bulk and the companion’s wind; for electrons, synchrotron emission and inverse Compton scattering off the radiation field of the companion. The figure also shows luminosities derived from XMM-Newton+NuSTAR data (our work) as well as ATCA and Fermi data taken from Corbet et al. (2019) and the 4FGL-DR2 catalog (Abdollahi et al. 2020; Ballet et al. 2020), respectively. All the references are in the figure.
