Large Neutrino Fluxes from Blasars?
High X-ray fluxes form 100 kpc-scale jets in AGN detected recently by
Chandra have challenged the existing theoretical models. It is not
clear how multi-TeV electrons which produce X-ray synchrotron
radiation can be deposited over the 100 kpc distance from the AGN
core. A recently proposed solution of this problem is the possibility
that the multi-TeV electrons are supplied by the beam of gamma-rays
with energies 10^15 - 10^18 eV. Gamma rays of these energies can be
produced by protons with spectrum peaked at 10^16 - 10^18 eV
accelerated in the core of AGN. Characteristic feature of the model
is that neutrino flux (in the band 10^15 - 10^17 eV) in direction
along the jet must be as large as the flux of GeV-TeV gamma rays
(which is detected by EGRET, HEGRA and other gamma-ray telescopes).
This means that the blasar-type AGNs would be seen by future neutrino
telescopes such as AMANDA-II, ANTARES, Pierre Auger Observatory,
ICECUBE, MOUNT and Telescope Array.
