Reassessing multimessenger quantum-spacetime astrophysics

Studies of particle propagation in a quantum spacetime
 have inspired a rich phenomenological program over the last decade. For
photons and neutrinos Planck-scale accuracy in testing some candidate quantum-spacetime
effects is  within reach of the Fermi and the IceCube telescopes. I
look at the first few years of data from Fermi and IceCube and compare
them to what was expected. Of particular interest would be the first
detection of a GRB neutrino, marking the start of multimessenger
quantum-spacetime astrophysics. No conclusive GRB-neutrino detection has
been so far reported by IceCube. But the available data can encourage speculations
about an exciting overlap between the astrophysics agenda and the
quantum-spacetime agenda of IceCube.
