Lepto-hadronic single-zone models for the electromagnetic and neutrino emission of TXS 0506+056

While active galactic nuclei with relativistic jets have long been prime candidates for the origin of extragalactic cosmic rays and neutrinos, the BL Lac object TXS 0506+056 is the first astrophysical source observed to be associated with…
