Abstract
The blazar TXS has been suggested to be a potential high-energy neutrino source thanks to the observations of IceCube, which found outburstlike neutrino emissions during 2014–2015 and 2017 in the transient emission search, and a local significance in a ten-year time-integrated search. The conventional one-zone jet model cannot explain the observed neutrino flux during outbursts due to the constraint from the x-ray flux, leading to proposals of multizone models (e.g., two-zone model) with multiple radiation zones. In literature, it has been shown that multizone models may consistently explain the high-state neutrino emission and the multiwavelength emission of TXS , while the quasi-steady-state long-term emission has not been well studied. In this work, we investigate a physically based model for the quasi-steady-state neutrino and electromagnetic radiation under the same framework, and successfully reproduce the multimessenger emission of TXS .
