Query: High-energy neutrinos from astrophysical accelerators of cosmic ray
  nuclei   Ongoing experimental efforts to detect cosmic sources of high energy
neutrinos are guided by the expectation that astrophysical accelerators of
cosmic ray protons would also generate neutrinos through interactions with
ambient matter and/or photons. However there will be a reduction in the
predicted neutrino flux if cosmic ray sources accelerate not only protons but
also significant number of heavier nuclei, as is indicated by recent air shower
data. We consider plausible extragalactic sources such as active galactic
nuclei, gamma-ray bursts and starburst galaxies and demand consistency with the
observed cosmic ray composition and energy spectrum at Earth after allowing for
propagation through intergalactic radiation fields. This allows us to calculate
the expected neutrino fluxes from the sources, normalised to the observed
cosmic ray spectrum. We find that the likely signals are still within reach of
next generation neutrino telescopes such as IceCube.
