Phys. Rev. Lett. 66, 2697–2700 (1991)High-energy neutrinos from active galactic nucleiSee Also: Erratum Received 3 April 1991; published in the issue dated 27 May 1991 We calculate the spectrum and high-energy ν background flux from photomeson production in active galactic nuclei (AGN), using the recent UV and x-ray observations to define the photon fields and an accretion-disk shock-acceleration model for producing high-energy particles. Collectively, AGN produce the dominant isotropic ν background between 104 and 1010 GeV, detectable with current instruments. AGN ν’s should produce a sphere of stellar disruption which may explain the ‘‘broad-line region’’ seen in AGN. © 1991 The American Physical Society URL:
