TL;DR: The detection of emission up to ∼31 GeV from the distant and short GRB, and no evidence for the violation of Lorentz invariance is found, which disfavour quantum-gravity theories in which the quantum nature of space–time on a very small scale linearly alters the speed of light.
Journal ArticleDOI
Surface Brightness and Evolution of Galaxies
TL;DR: In this paper, the authors proposed the use of apparent surface brightness, which depends only on the redshift and is independent of the cosmological model and the inhomogeneities in the universe, for observational determination of the evolution of galaxies.

Journal ArticleDOI
On the Nonthermal Emission and Acceleration of Electrons in Coma and Other Clusters of Galaxies
TL;DR: In this article, the authors derived a spectrum for the radiating electrons and discussed possible acceleration scenarios for its production, and showed that continuous and in situ acceleration in the ICM of the background thermal electrons is difficult and requires unreasonably high energy input.
