The spectrum of isotropic diffuse gamma-ray emission between 100 MeV and 820 GeV
The Fermi LAT collaboration, M. Ackermann, M. Ajello +142
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a res…
The Spectrum and Morphology of the Fermi Bubbles
LAT Collaboration
The Fermi bubbles are two large structures in the gamma-ray sky extending to above and below the Galactic center. We analyze 50 months of Fermi Large Area Telescope data…
Inferred cosmic-ray spectrum from -LAT -ray observations of the Earth's limb
LAT Collaboration, M. Ackermann, M. Ajello +150
Recent accurate measurements of cosmic-ray (CR) species by ATIC-2, CREAM, and PAMELA reveal an unexpected hardening in the proton and He spectra above a few hundred GeV, a gradual…
Multifrequency Studies of the Peculiar Quasar 4C +21.35 During the 2010 Flaring Activity
M. Ackermann, M. Ajello, A. Allafort +288
The discovery of rapidly variable Very High Energy (VHE; E > 100 GeV) gamma-ray emission from 4C +21.35 (PKS 1222+216) by MAGIC on 2010 June 17, triggered by the high activity dete…
Fermi-LAT Detection of Gravitational Lens Delayed Gamma-ray Flares from Blazar B0218+357
C. C. Cheung, S. Larsson, J. D. Scargle +23
Using data from the Fermi Large Area Telescope (LAT), we report the first clear gamma-ray measurement of a delay between flares from the gravitationally lensed images of a blazar.…
