TL;DR: The ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes as mentioned in this paper, which is an international initiative to build the next generation instrument, with a factor of 5-10 improvement in sensitivity in the 100 GeV-10 TeV range and the extension to energies well below 100GeV and above 100 TeV.

TL;DR: The Cherenkov Telescope Array (CTA) as discussed by the authors is a very high-energy (VHE) gamma ray observatory with an international collaboration with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America.

TL;DR: In this article, the authors describe the development of the Galactic Interstellar Emission Model (GIEM) which is the standard adopted by the LAT Collaboration and is publicly available, based on a linear combination of maps for interstellar gas column density in Galactocentric annuli and for the inverse-Compton emission produced in the Galaxy.

TL;DR: In this paper, the uncertainty of the Galactic Center (GC) excess spectrum and morphology due to uncertainties in cosmic-ray source distributions and propagation, uncertainties in the distribution of interstellar gas in the Milky Way, and uncertainties due to a potential contribution from the Fermi bubbles.

TL;DR: The Cherenkov Telescope Array (CTA) as mentioned in this paper is the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond, covering a huge range in photon energy from 20 GeV to 300 TeV.
