TL;DR: In this article, the authors reported upper limits on the photon flux in the range 0.2-100 GeV towards a sample of observed clusters (typical values 1-5 x 10^-9 ph cm^-2 s^-1) considering both point-like and spatially resolved models for the high energy emission, and discuss how these results constrain the characteristics of energetic leptons and hadrons, and magnetic fields in the intracluster medium.

TL;DR: The first direct observation of a break in the spectrum of a high luminosity blazar above 100 MeV was reported in this article, and it is likely direct evidence for an intrinsic break of the energy distribution of the radiating particles.

TL;DR: In this paper, the first detection of orbital periodicity in high-energy gamma rays (20 MeV-100 GeV, HE) was made using LS I +61°303 data from the Fermi Gamma-Ray Space Telescope between 2008 August and 2009 March.

TL;DR: The gamma-ray spectra of the pulsars are power law in nature with exponential cutoffs at a few Ge V, as has been found with most other pulsars as discussed by the authors.

TL;DR: In this paper, the discovery of eight gamma-ray pulsars in blind frequency searches using the LAT, onboard the Fermi Gamma-ray Space Telescope, was reported, and the timing models, light curves, and detailed spectral parameters of the new pulsars were presented.
