Fermi Large Area Telescope Observations of the Active Galaxy 4C +55.17: Steady, Hard Gamma-Ray Emission and its Implications
Steady Hard Gamma-Ray Emission Implications
2011/9/29
We report Fermi/LAT observations and broad-band spectral modeling of the radio-loud active galaxy 4C +55.17 (z=0.896), formally classified as a flat-spectrum radio quasar. Using 19 months of all-sky s...

We report on the search for 0.1{10 GeV emission from magnetars in 17 months of Fermi Large
Area Telescope (LAT) observations. No signi cant evidence for gamma-ray emission from any of the currently-k...
