Recent observations are suggesting that active galactic nuclei (AGNs) play in the production of high-energy neutrinos. Even if blazars are good candidates to be neutrino emitters, our understanding of the physical processes and locations of production remains limited. In this study, we focus on one object, 5BZB J0630-2406, which is one of the blazars recently associated with neutrino emission (Buson et al. 2022). Modelling the quasi-simultaneous, broad-band spectrum energy distribution (SED) of the selected blazar, we explore various scenarios from purely leptonic to lepto-hadronic models, testing the inclusion of external photon fields. This theoretical study provides a complementary testing ground for the proposed neutrino – blazar association. Despite being historically classified as a BL Lac, our results show that 5BZB J0630-2406 is a high power FSRQ, producing a neutrino flux within the reach of the IceCube detector.
