No Gamma-Rays from Magnetars
Fermi has looked for gamma-rays from magnetars from 100 MeV to 10 GeV and found none. This eliminates (or makes things really difficult) for some models of the hard x-ray emission from magnetars such as mine ( http://lanl.arxiv.org/pdf/astro-ph/0502349 ). Nothing ventured, nothing gained.
