Design concepts for the Cherenkov Telescope Array CTA: An advanced facility for ground-based high-energy gamma-ray astronomy

Marcos Daniel Actis, +685 more
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.
Journal ArticleDOI

Introducing the CTA concept

B. S. Acharya, +982 more
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.
Journal ArticleDOI

Evidence for correlated changes in the spectrum and composition of cosmic rays at extremely high energies.

TL;DR: The Utah Fly's Eye detector has revealed a change in the cosmic ray composition which is correlated with structure in the all-particle energy spectrum, implying that the highest energy particles originate in the contemporary era of the Universe.
Journal ArticleDOI

Detection of a Cosmic Ray with Measured Energy Well beyond the Expected Spectral Cutoff due to Cosmic Microwave Radiation

TL;DR: A 51-joule (320 +/- 90 EeV) cosmic ray was detected by the Fly's Eye air shower detector in Utah as mentioned in this paper, which is substantially greater than the energy of any previously reported cosmic ray.
