Sahakyan" ], "comment": "Accepted for publication in ApJ", "categories": [ "astro-ph.HE" ], "abstract": "The observation of IceCube-170922A event from the direction of TXS 0506+056 when it was in its enhanced $\\gamma$-ray emission state offers a unique opportunity to investigate the lepto-hadronic processes in blazar jets. Here, the observed broadband emission of TXS 0506+056 is explained by boosted synchrotron/synchrotron self Compton emission from the jet whereas the $\\gamma$-ray data observed during the neutrino emission- by inelastic interactions of the jet-accelerated protons in a dense gaseous target. The proton energy distribution is $\\sim E_{p}^{-2.50}$, calculated straightforwardly from the data obtained by Fermi-LAT and MAGIC and if such distribution continues up to $E_{c,p}=10$ PeV, the expected neutrino rate is as high as $\\sim0.46$ events during the long active phase of the source or $\\sim0.15$ if the activity lasts 60 days. In this interpretation, the energy content of the protons above $>$ GeV in blazar jets can be estimated as well: the required proton injection luminosity is $\\simeq2.0\\times10^{48}\\:{\\rm erg\\:s^{-1}}$ exceeding $10^3$ times that of electrons $\\simeq10^{45}\\:{\\rm erg\\:s^{-1}}$ which are in equipartition with the magnetic field. As the required parameters are physically realistic, this can be an acceptable model for explanation of the neutrino and $\\gamma$-ray emission from TXS 0506+056.", "revisions": [ { "version": "v1", "updated": "2018-08-16T19:18:44.000Z" } ], "analyses": { "keywords": [ "neutrino emission", "boosted synchrotron/synchrotron self compton emission", "ray emission state offers", "blazar jets", "proton energy distribution" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
