Description
There have been recent population studies supporting the idea that radio-loud blazars can be the potential source of high-energy astrophysical neutrinos being observed by IceCube. The understanding of neutrino production from these sources is intimately connected to explaining their multi-wavelength spectra as well. In this talk, ongoing work will be presented in modelling the lepto-hadronic spectral energy distribution (SED) for the neutrino-candidate blazar PKS 1749+096 in which both, the bulk properties and the particle distribution in the emission region, are anchored directly using parsec-scale VLBI observations of the jet and the corresponding spectral index map. When combined with physically motivated assumptions about jet processes, this approach allows modeling the SED from radio to gamma-rays without using numerical fitting to archival data. Thus, the talk attempts to motivate using radio observations as an anchor for improving our understanding of multi-messenger emission from neutrino-candiate blazars.
